Considering the central importance of Galen's writings in medicine from the time he wrote well through the sixteenth and even the seventeenth century, and the need for physicians to make sense of such a large number of his texts, it does not seem surprising that the first printed bibliography of any medical author would be De divisione librorum Galeni by the fourteenth century Italian physician Gentile da Foligno (Gentilis Fulginas) who appears to have been one of the first European physicians to perform a dissection on a human (1341). Gentile's very brief listing was first published in the collective volume, containing over ten short texts, entitled Articella su Opus artis medicinae edited by Franciscus Argilagnes of Valencia, and published in Venice by Hermannus Liechtenstein on March 29, 1483. The Articella was used as a textbook or reference work in the early medical schools. Among the other works published in that volume was the first printing (in Latin) of the Hippocratic Oath.
