摘要：In this article we introduce to the public knowledge a new collection of works by Francisco de Herrera, el Viejo, unknown until now, that enlarge considerably his catalogue. Within them we point out a set of architectural preparatory drawings for the gypsum-klin (yeserías) of the Convento de Santa Buenaventura in Sevilla, and also the discovery one architect's notebook that shows an important series of Sevillian designs. At the same time, we remark different aspects of his formation as painter, mentioning the possible influence of Pablo de Céspedes and some flemish masters like Martin de Vos, and we allude to the contacts, not referred until the present day, with Ribera and the young Alonso Cano. We also bring up some information about certain lost works, not considered in previous studies, and some problematic attributions.
