Main (Thompson) Library location: South wing -- Fifth window. Sixtus Riessinger (c.14-- – c.1505) matriculated at the University of Freiburg in 1462, and became a priest in Strasbourg shortly thereafter. As was customary for priests, he learned the trade of printing during his ministry from Henry Eggestein. Riessinger's first documented book dates to 1467, when he printed an edition of Epistolaeby St. Jerome in Rome. In the colophons of his books, he referred to himself as "Riessinger from Argentina," an archaic Latin reference to the city of Strasbourg. He then moved his press to Naples, and began to issue productions of popular contemporary literature and classical texts. His most notable titles include Florio e Biancafioreby Giovanni Bocaccio and Super Digesto novo by Baldus de Ubaldis. Riessinger eventually moved back to Rome, where books attributed to him are dated to as late as 1493. The printer's mark of Sixtus Riessinger is simple, containing only an arrow that intersects with another diagonal object. In the full printing device, a female figure, intended to represent the mythological Sibylla Persica, supports an escutcheon bearing the mark. A scroll flowing above the woman presents the letters S.R.D.A., an abbreviation for "Sixtus Riessinger de Argentina."
