Woodcut of the medieval cell doctrine from Guillaume Le Lièvre (fl. c. 1520)

Woodcut of the medieval cell doctrine from French author Guillaume Le Lièvre (Gulielmus Leporeus; fl. c. 1520). The olfactory bulbs are depicted as a pair of round structures at the bridge of the nose, and both show projections from these structures to the sensus communis in the anterior portion of the anterior ventricle. The same woodcut was printed in editions in 1520 and 1523. (Source: Österreichische Nationalbibliothek [Austrian National Library], Vienna. See: Lanska DJ.
