This work constitutes the final portion of Boethius' Opera printed by Giovanni and Gregorio de' Gregori in Venice, between 1491 and 1492 and issued under the collective title "H[a]ec sunt opera Boetii, qu[a]e in hoc volumine continentur ...". The foliation and signature series are constitent throughout the Opera. The Library of Congress catalog notes the number of institutions holding this part only is suggestive of it having been issued separately for sale.
