Abstract

This article explores Albert the Great’s conclusions over the embryological ‘controversy’ among physicians and philosophers, particularly with regard to the existence of a “female sperm”. First, Albert’s approach to the relationship between philosophy and medicine is confronted to that of Thomas Aquinas. Then, the hybrid nature of Albert’s embryology, which can be placed precisely halfway between natural philosophy and medicine, is investigated. By closely following Avicenna’s De animalibus, one of Albert’s main sources, the following part of the article sets out the main elements of the controversy over generation that both Avicenna and Albert had, in turn, inherited from their Greek predecessors, namely: the identification of the first organ to be formed in the foetus, the origin of seminal matter, and the related issue of the formalitas and materialitas of both female and male seeds. I argue that the equivocal nature of the term sperma, when attributed to the female contribute to generation, can be understood in at least three different but interconnected senses, which complicated the medieval debate on the precise nature and function of this fluid.
