FIRST EDITION of the first systematic study of the structure, distribution and position of the venous valves. Although the valves of the veins had been observed previously by G.B. Canano and Amato Lusitano, Fabrici studied them anew on the basis of his own observations. Perhaps because he analyzed anatomical structures in terms of their purpose, he interpreted the function of the valves as slowing down the influx of blood in order to distribute it more evenly to the various parts of the body. Although Fabrici's analysis was in part erroneous, De venarum ostiolis became his most influential work, in that it inspired his student, William Harvey, to conceptualize the circulation of the blood. Fabrici's plate illustrating the valves of the arm was the model for the plates illustrating Harvey's De motu cordis (see lot 502).
