Medieval recorder from Tartu, Estonia/Keskaegne plokkfloot tartust.
Tvauri, Andres ; Utt, Taavi-Mats
Introduction
In the centre of Tartu in the courtyard of 15 Ulikooli Street
archaeological excavations were carried out in summer 2005 and spring
2007 by the University of Tartu directed by Andres Tvauri. The aim of
those excavations was to investigate the whole courtyard area (115 sq. m
in total) archaeologically in order to enable the construction of
underground rooms. Six wooden cesspits from 14th-16th centuries were
found from the area (Tvauri & Bernotas 2005; 2006; Tvauri 2007).
Among other fords a completely preserved wooden recorder was found
in 2005 from one of the latrines (Fig. 1). Because a medieval recorder,
as well as medieval musical instruments in general, is an extremely rare
find, it deserves a publication of its own.
Context of the find
The recorder was found from the centre of medieval Tartu (Fig. 2)
in medieval and also current back yard area, from latrine no. 1b. The
latrine was made from pine logs (Fig. 3) and its measurements were 1.8 x
1.8 m, the height being 1.9 m (15 layers of logs). On the upper side of
the cesspit, at the height of the 1st-2nd log layers from the top, there
was a thin layer of decayed wood, seemingly originating from boards
covering the cesspit. Underneath, the pit was filled with thick and
sticky layer of excrements, containing abundant branches, wood chips,
fire-sticks, textile remains, animal and fish bones, cherry and plum
stones, shells of Persian walnuts, fragments of wooden vessels,
potsherds, fragments of window glass and other finds.

Archaeological objects of this kind are common in Tartu--at least
35 wooden cesspits dated to the 13th-16th centuries have been found and
investigated in town. As the medieval cultural layer of Tartu is in most
cases situated in wet and oxygen-free environment of the low and flat
river valley, the organic material found there (wood, textile, leather,
bone, etc.) is often very well preserved. Conditions for the
preservation of organic material are particularly favourable in the
latrines filled with excrements.
The contents of the cesspit at 15 Ulikooli Street can be
interpreted as one stratigraphic unit. It means that the entire filling
of the pit has deposited in quite similar conditions in a relatively
short time. Only on the very bottom of the pit there was a 50-cm thick
layer different in content and with no finds. The recorder was situated
near the centre of the latrine, 1 m below the survived upper log.
[FIGURE 3 OMITTED]
Dating of the Tartu recorder
Other finds from the same layer can be used for dating the
recorder. For example, there was a stoneware jug 14 cm in height (TM A
141: 70), which originates from southern Lower Saxony where vessels with
similar characteristics were produced in the second half of the 14th
century (Stephan 1981, pl. 43: 1-3; Russow 2006, 74-75). In addition
fragments of several jugs from Siegburg, Rhineland were found. A
completely preserved jug (Fig. 4) can be dated to the period 1290-1400
(Russow 2006, fig. 12: 1; personal comment by Erki Russow). An upper
part of a bulhy jug is almost completely preserved (TM A 141: 505); it
obviously belongs to the turn of the 14th-15th centuries (personal
comment by Erki Russow). Pieces of Jacoba jug (TM A 141: 72) originating
from western part of Saxony, Waldenburg, were also found. Those jugs are
considered to date to the period 1375/1400-1525/1550 (Scheidemantel
2005, 110-111). Besides stoneware, fragments of two earthenware vessels
(TM A 141: 550, 552) came to light from the latrine. We are dealing with
pottery of NW-Russian-style, which can be dated to the 14th-15th
centuries based on the rim shapes of the vessels and ornaments of sparse
or wavy lines made with stick (Tvauri 2000, 105-107, fig. 9; [TEXT NOT
REPRODUCIBLE IN ASCII] 2002, 12, fig. 4: 1-5).
[FIGURE 4 OMITTED]
Beaker or beakers of thin clear glass with blue glass-string
decorations (TM A 141: 44-55) were also found from the cesspit.
Fragments of such beakers have been found only in towns of the Baltic
Sea region from deposits of the 14th-early 15th century. In Finland this
kind of glass findings from the layers of the town of Turku have been
dated to the period 1360-1410 (Haggrbn 2003, fig. 4; 2005, fig. 3: 2).
An upper part of a small glass bottle, the so-called Ribbenflasche (TM A
141: 543) is a unique find in Estonia it is the first and so far the
only one found here. Such glass bottles have been uncovered elsewhere in
Europe in the 13th-14th-century context (Baumgartner & Krueger 1988,
270-280). A push key spring lock made of iron (TM A 141: 154) can be
dated to the 14th century or to the first half of the 15th century
([TEXT NOT REPRODUCIBLE IN ASCII] 1982, fig. 3, type [TEXT NOT
REPRODUCIBLE IN ASCII]).
Summing up the dates of the finds from the cesspit in question one
can see that in most cases they belong to the 14th-15th centuries. In
the case of those objects dated to the 15th century it is also possible
that they come from the turn of the 14th-15th centuries. Based on the
finds, the content of the cesspit most likely comes from the second half
of 14th century. The rest of the archaeological finds from the latrine
also fit into the proposed period.
Fortunately it was possible to date the logs of the latrine using
dendrochronological method. The logs were cut down in 1335 (Bernotas
2008, in print).
Summing up the information presented above we can date the contents
of the latrine to the period between 1335 and the end of the 14th
century. However, this does not show the time when the instrument was
made but the time when it was deposited in the ground.
To date the recorder itself, a radiocarbon dating (AMS) was
conducted in the Dating Laboratory of the University of Helsinki in
winter 2007. For that purpose a sample of wood was taken from the
recorder, which was dated to 690[+ or -]30 BP (Hela-1338). When
calibrated with computer program OxCal v.3.10, two possible time
intervals were achieved with 95.4% certainty (Fig. 5), first fitting to
12601315, and second 1355-1390.
It must be considered that the radiocarbon dating represents the
age of the material that the instrument is made of. More precisely even,
the time when the tree-rings of the wood sample were formed. If the
recorder was made of the inner part of a tree, the result of radiocarbon
dating can be tens of years older than the actual time of cutting down
the tree. Additionally, it can be presumed that the instrument was made
of carefully dried wood and it could have been in use for many years.
Considering the above-mentioned aspects, it is quite plausible that the
recorder was produced at the beginning of the 14th century. Thus the
active use of the instrument falls into the first half of the 14th
century.
In the 14th century, Tartu was an important and wealthy Hanseatic
city, the main income of which came from transit-commerce between
western and northern European Hanseatic towns and Novgorod and Pskov in
Russia. At that time the Old Livonian towns belonged explicitly to
Northern German, i.e. Hanseatic cultural sphere. The latrine where the
Tartu recorder was found was probably situated on the land of a wealthy
German merchant. Both the central position of the plot of land in town
(near the market square and next to the largest church in town) as well
as fragments of imported glass-beakers and exotic archaeobotanic finds
(grape seeds, shells of Persian walnuts, plum stones, peppercorns),
which in this case can be described as luxury items, give evidence of
the lavatory owner's wealth.
[FIGURE 5 OMITTED]
Tartu recorder
The recorder is made of maple (Acer platanoides). (1) There are
ornamental rings at the mouthpiece end (Fig. 6). External outline of the
recorder is nearly cylindrical, resembling a bone in shape. Directly
after uncovering (being soaked in water) the total length of the
recorder was 250 mm and the largest diameter was 30.7 mm on the
mouthpiece end. Its bore has a diameter of 12 mm at the end of foot
section.
[FIGURE 6 OMITTED]
The bore seems to be near cylindrical, conic by the block and
mildly descending at the other end of the instrument. Still there is no
doubt that the violation of cylindrical form is deliberate and not the
outcome of deformation. The bore is slightly bent, while the existence
of dirt inside the instrument and the oval form of the bore make it hard
to measure the exact dimensions.
There was a crack at the end of the instrument already when found.
Fortunately this does not go right through and will not affect the bore.
The instrument was slightly bended, which is rather surprising in case
of maple-wood. This was probably caused by extreme humidity and the
pressure of the soil. On the surface of the recorder there are some
notches inflicted in the course of excavations. Luckily they are in such
places where they do not affect the musical qualities of the instrument.
The recorder was conservated in the Department of Archaeology of the
University of Tartu. In the process of boiling the instrument in
paraffin its dimensions diminished to some extent.
The windway and block of the instrument are well preserved and very
precisely made especially when compared to not so accurately prepared
labium. The latter has a bowed edge which withdraws in the centre. It
seems, however, that the labium is not worn out in any way and we see
the original shape.
The block is made from a birch branch (Betula) and is 23 mm in
height (Fig. 7). Amazing is the even concavity and high quality (of
refinement) of the block's windway which is characteristic also to
instruments from later periods. The block has a conical shape with a
diameter of 11.7-12.3 mm. The more surprising is a small hole drilled
horizontally through the instrument and block (Fig. 8). An X-ray photo
shows spots on the edges of that hole where the Roentgen rays have
reflected back (oxide?). It can be assumed that the block was fixed with
a metal pin, although there was no need for that because of the conicity
of the block. As the block is made of birch which reacts to changing
humidity and temperature more than cedar, which was used as
block-material in later periods, the block could have been made with
extra room for expanding. In that case it would have needed a metal rod
for additional fixing. We must not exclude the possibility that the rod
was meant for hanging the instrument, especially while taking in account
its small parameters. The blowing end of the recorder is not beaked (as
usual by modern recorders in order to ascertain the best position for
blowing) but flat.
[FIGURE 7 OMITTED]
[FIGURE 8 OMITTED]
Unlike all other surviving medieval recorders, the Tartu recorder
has finger holes in one row and the lower, seventh hole is not doubled.
This is not very surprising considering the small size of the
instrument. Remarkable is the regular placing of the finger holes and
similarity of diameters of the holes. All the holes are drilled in the
direction of the labium. The finger holes are cylindrical and almost
entirely not undercut.
Compared with the modern classification of recorder sizes and
pitches it is closest to a low sopranino at [a'sup.1] = 440 Hz.
Indeed, this is only contemporary classification which does not claim to
be potential medieval standard. The lowest tone of the instrument is ca
30 cents lower than second octave F, and the seventh finger hole
produces a half tone, unlike the later standards.
The instrument has survived so well that it makes sound when blown.
The range of the Tartu recorder is two octaves and a second.
Unfortunately we cannot decide upon the original range of the instrument
with certainty. It is possible that the shrinkage of wood in the process
of conservation and the presence of some dirt (urinary calculus?) inside
the bore have narrowed it, and paradoxically, the range could have even
widened. Despite the fact that such theoretical possibility exists it is
quite likely that we are dealing with the original range of the
recorder. Considering that the range of most renaissance recorders was
an octave and major sixth, such a wide range in such an old instrument
is definitely surprising. Already external observation revealed a
relatively large window compared to the small parameters of the
instrument which also did not predict such a wide range.
Hundreds of years in wet environment, deformation under the weight
of the soil and later conservation have undoubtedly changed the
dimensions of the instrument, among others placing labium and windway
towards each other. Thus the current musical qualities of the Tartu
recorder, sound, articulation and temperament do not correspond to the
initial ones and describing them as they are now would only discredit
the instrument. Additional information to the experts is the fact that
there is no flat edge on the end of windway and it is very delicate,
almost invisible on the block.
All the materials used to produce the instrument were common in
Estonia but considering the wide geographic scope of the cesspit-fords
it is very likely that the recorder is not of local origin.
Tartu recorder in the context of medieval recorders
The number of recorders from the 14th century and earlier period is
not known exactly because in most cases only fragments of instruments
have been found. In addition to labium, block and windway the
classificatory features of recorder are holes for seven fingers and a
thumbhole which serves as an octaving vent. Thus it is hard to
distinguish recorder and whistler in case of incomplete exemplars. The
latter was in extensive use as a folk instrument in different countries.
The oldest almost completely preserved recorder is the
"Dordrecht Recorder". This was discovered in 1940 from the
moat surrounding the ruins of the Huis to Merwede castle, about 3 km
east of the town of Dordrecht, Holland. "Dordrecht Recorder"
is dated to the 14th century (Weber 1976; Rowland-Jones 1996, 17) or
even to the 13th century (Hakelberg 1995, 11). A second well-know
medieval recorder dating from the 14th century is a more or less
complete instrument found in a latrine in Gottingen, Germany, in 1987
(Hakelberg 1994; 1995; Reiners 1997). A fragment of a third 14th-century
recorder has recently been found near Stuttgart, southern Germany. It
was excavated from the sediment of the mill channel of the
Carmelite' Monastery in Esslingen. Although all the forger-holes
have not been preserved it can be regarded as a recorder due to the very
same characteristic turning proule as has the Gottingen recorder (Lander
2006). A recorder found during the excavations in Poland, Elbl4g, is
also worth mentioning (Poplawska 2004) although any further
investigations about the instrument have not yet been published.
According to preliminary data the recorder probably dates from the 15th
century.
Unfortunately the list of reliably medieval recorders hereby ends.
As none of the forementioned instruments makes sound, nor are they
completely preserved it is impossible to overestimate the importance of
the Tartu recorder.
How to act in case of finding medieval woodwind musical instrument?
Musical instruments constitute a very small part of archaeological
fords but the more valuable is the information gained through them.
Taking into account the experience received with finding, conservation
and documentation of the Tartu recorder, we would like to give some
suggestions of how to act in case an instrument is found.
In case of woodwind instruments the level of accuracy necessary in
measuring the instruments is far greater than usually presumed. For
instance, in case of recorder, the minimal level of precision would be
0.1 mm. Concerning acoustics, bore and labium, block and windway are
remarkably interesting in addition to the placing of finger-holes. As it
is usually beyond the capacities and competence of archaeologists (and
unskilled measuring can cause damages), a specialist should be contacted
immediately.
Measuring of the instrument should be done already before the
conservation of the find. Till then it is appropriate to place the
instrument hermetically into a plastic bag with some soil that
surrounded it. If the measuring cannot be done immediately the artefact
should be deep frozen to avoid deformation.
While documenting, scanning the object is preferred to traditional
photographing. Advantages are lack of aberrations and noticeably better
quality of the image. In case only camera can be used in addition to
ruler placed next to the instrument while photographing, distance
between the object and camera should be clarified. This would simplify
to find photographic aberrations later. Such a precision may seem
exaggerated but measuring the wet instrument (and doing necessary
recalculations) would give a result quite close to the original. This
again would enable to make an exact copy of the recorder and thus
reconstruct the medieval musical scale.
Conclusions
The Tartu recorder, which was found in 2005 from a latrine, and can
be dated to the 14th century, is an extremely rare finding and as yet it
is the best-preserved medieval recorder ever found. The instrument
widens the geography of recorder use in Europe significantly and shifts
forward in time the implementation of several instrument-making methods.
But namely due the rareness of the find we must be very careful in
making generalizations regarding recorders of that period. There is no
doubt that the instrument raises many questions for both theoreticians
and practicians and at least some of them will get answers with the help
of feasibly precise reconstructions and their use in practice.

Ulikooli 15 hoovist arheoloogiliste kaevamiste kaigus keskaegsest
lampkastist mude leidude hulgas ka terviklikult sailinud puidust
plokkfloot (joon 1). Pilh leiukohaks oh 1,8-meetrise kuljepikkusega ja
keskmiselt 10 cm paksustest koorimata mannipalkidest ristpalktehnikas
valmistatud kast (joon 3), mis oli sailinud 1,9 m (15 palgikihi)
korgusena. Kasti taitis valjaheidetest ja keskaegsest rampsust
moodustunud tihke orgaaniline mass.
Floodi dateerimiseks annavad pidepunkti sellega samast kihist
saadud muud leiud (naiteks joon 4), mis parinevad 14.-15. sajandist, ent
15. sajandi dateeringuga esemete puhul on voimalik ka nende paritolu 14.
sajandi lopust. Seega parineb uuritud lampkasti sisu koige
toenaolisemalt 14. sajandi teisest poolest. Kasti palkide
dendrokronoloogilisel dateerimisel saadi tulemuseks, et need on
langetatud 1335. aastal. Plokkfloodist voetud puiduproovi radioaktiivse
susiniku meetodil dateerimine andis pilli materjali vanuseks 690[+ or
-]30 radiosusinikuaastat (Hela-1338). Tulemust kalibreerides saadi kaks
voimalikku dateeringut kalendriaastates--1260-1315 ja 1355-1390 (joon
5).
Pill on treitud uhes tukis harilikust vahtrast. Huulikupoolses osas
asub treitud ringornament (joon 6). Tegemist on peaaegu silindrilise
plokkfloodiga, mis oma valiskujult meenutab pisut konti. Pill on
ligikaudu 250 mm pikk ja suurim labimoot on huulikupoolses otsas 30,7
mm. Tuulekanali labimoot alumisest otsast moodetuna on 12 mm. Pilli oos
on peaaegu silindriline, ploki juures kooniline ja pilli teises otsas
kergelt kahanev. Instrumendi tuulekanal on vaga hasti sailinud ja ka
tehtud, eriti vorreldes pisut hooletumalt valmistatud laabiumiga, mida
iseloomustab kaarjas keskelt kaugenev serv. Tundub siiski, et ka
laabiumi kulumine on minimaalne ja tegu on originaalkujuga. Plokk on
valmistatud kaseoksast ja on 23 mm pikk (joon 7). Selle puhul hammastab
hilisematest pillidest tuttav ploki tuulekanali uhtlane nogusus ja Urge
viimistlustase. Plokk on kullalt kooniline: selle labimoot on 11,7-12,3
mm. Seda ullatavam on poigiti huulikut ja plokki labiv ava (joon 8).
Pillist tehtud rontgenifotol on ava servades naha laigud, kust
rontgenikiired on tagasi peegeldunud (metallioksiid?). See voimaldab
oletada, et pilli ja plokki hibis algselt metallist tihvt. Silindrilise
ploki puhul oleks sellel olnud plokki ukseeriv ulesanne, mille jarele
tundub antud juhul otsene vajadus puuduvat. Siiski on voimalik, et kuna
plokk on kasest ja selle puidu reageerimine muutuvale niiskusele ning
temperatuurile on suurem kui hiljem levinud plokimaterjalil seedripuul,
vois plokk olla tehtud teadlikult paisumisvaruga, noudes siiski
taiendavat kinnitamist tihvtiga. Pilli mootmeid arvestades ei saa
valistada, et tibvtil oli kinnituskoht plokkfloodi kaela voi voole
riputamiseks. Plokkflootidel on enamasti mugavama puhumisasendi
saamiseks huulikupoolses otsas iseloomulik loige, mis algab tavaliselt
tagakuljelt ja jouab valja peaaegu tuulekanali alguseni, Tartu pillil
see puudub. Erinevalt koikidest teistest sailinud keskaegsetest
plokkfloodidest asetsevad sormeavad uhel joonel ja viimane, seitsmes
ava, ei ole dubleeritud. Tahelepanuvaarne on sormeavade paigutuse
regulaarsus ja nende diameetrite samasus. Koik sormeavad on puuritud
nurga all suunaga laabiumi poole. Samas on koik avad peaaegu
silindrilised ja neid ei ole alt laiendatud.
Oma suuruselt voib Tartu plokkfloodi vorrelda kaasaegse haalestuse
[a'sup.1] = 440 Hz subtes madala F-sopraninoga. Puhudes teeb pill
haalt. Pilli alumine noot on 2. oktavi f-noodist ligikaudu 30 senti
madalam ja seitsmes sormeava annab erinevalt hilisematest standarditest
pooltooni. Tartu plokkfloodi ulatuseks on kaks oktavit ja sekund.
Kahjuks ei saa taie veendumusega otsustada pilli algse ulatuse ule.
Voimalik, et plokkfloodi konserveerimisest tulenev puidu mootmete
muutumine ja moningane mustus on teinud mensuuri kitsamaks ning seega
vois ulatus isegi suureneda. Hoolimata sellisest teoreetilisest
voimalusest on siiski toenaoline, et tegemist on plokkfloodi
originaalulatusega. Arvestades seda, et ka enamiku
renessanssplokkfloodide ulatuseks oli oktav ja suur sekst, on nii varase
perioodi pilli nii suur ulatus fillatav. Juba instrumendi valisel
vaatlusel naeme selle pilli mootude kohta kfillalt suurt akent, mis
samuti ei lubaks nonda suurt ulatust prognoosida.
Aastasadadepikkune seismine marjas keskkonnas, deformeerumine
pinnase raskuse mojul ja hilisem konserveerimine on kahtlemata muutnud
pilli mootmeid, sealhulgas ka laabiumi ning tuulekanali omavahelist
asetust. Seeparast ei vasta Tartu plokkfloodi tanased muusikalised
kvaliteedid, nagu tamber, artikulatsioon ja temperatsioon, algsetele
omadustele. Erialaspetsialistidele annab lisaks eelkirjeldatud
detailidele lisainfot ka fakt, et tuulekanali lopus ei ole faasi ja
plokil on see vaga delikaatne, et mitte oelda vaevumargatav.
Koik pilli tegemiseks kasutatud materjalid olid tavalised ka
Eestis, kuid lampkasti leidude laia geograafilist haaret arvestades on
siiski toenaoline, et pill ei ole kohaliku paritoluga.
14. sajandist voi varasemakt ajast sailinud plokkfloodide arv ei
ole tapselt teada, kuna pohiliselt on leitud vaid pillide fragmente.
Plokkfloodi tunnuseks on lisaks laabiumile, plokile ja tuulekanalile ka
seitse sormeava ning pilli vastaskuljel paiknev poidlaava. Seeparast on
mittetaielike leidude puhul raskusi plokkfloodi ja vilepilli
eristamisega. Viimased olid rahvapillidena eri maades laialdaselt
kasutusel.
Vanimaks peaaegu tervikuna sailinud plokkfloodiks on Hollandist
leitud nn Dordrechti floot, mis on dateeritud 14. voi isegi 13.
sajandiga. Teiseks tuntumaks keskaegseks plokkfloodiks on Saksamaalt
Gottingenist leitud pill, mis parineb 14. sajandist. Katke 14. sajandi
plokkfloodist on leitud ka Saksamaalt Esslingeni karmeliitide kloostri
veskikraavi pohjast. Mainida voib ka Poolast Elblagist leitud
oletatavasti 15. sajandist parinevat plokkfloodi.
Kuna ukski eelpool loetletud pillidest haalt ei tee ega ole ka
tervikuna sailinud, siis on Tartu pilli kohta keskaegsete plokkfloodide
seas raske ule hinnata. Tartu plokkfloodi naol on tegemist filiharuldase
leiuga, mis on seni teadaolevalt koige paremini sailinud keskaegne
