Master printer and innovator Aldus Manutius produced some of the finest early books printed in Venice. His extraordinary collection, the Scriptores Astronomici Veteres, included four astronomical texts that date from the Hellenistic period through imperial Rome. This star-studded Leo is one of many constellations illustrating the Greek poet Aratus's Phaenomena, one of the few illustrated works produced by the Aldine Press (they're modeled on earlier woodcuts produced by another Venetian printer, Erhard Ratdolt for his star atlas in 1482). Leo has special resonance for Hogwarts students as the sign of both Harry Potter and J.K. Rowling herself: both were born on July 31, and the lion is the regal animal behind Harry's house. Hail, Gryffindor!
