Main (Thompson) Library location: South wing -- End window. The earliest available records concerning Caligula de Bazaleriis (c.14-- – c. 15--) locate him in Bologna in 1490. There he may have begun to work with printer and relative, Bazalerius de Bazaleriis, who published books dated as early as 1480. De Bazaleriis printed independently for over a decade, from 1492 to 1504. Over the course of this relatively short career, however, he managed to issue a number of significant publications, especially the works of Italian writers and humanists including Giovanni Garzoni, Dante Alighieri, and Giovanni Bocaccio. The latest work attributed to de Bazaleriis is entitled Bucolica by Titus Calpurnius Siculus from 1504. Caligula de Bazaleriis used a modified orb-and-cross as the basis of his mark; the lower portion of the symbol is a heart instead of the traditional orb. Within the heart are the initials K.B., likely references to his name, suggesting that he originated outside of Italy. The two-barred cross is typically known as a "patriarchal cross."
