Prologomena in Galenum, in tres partes divisa written by physician, naturalist, and bibliographer, Conrad Gessner (Gesner), and issued in volume one of Cl [audius] Galeni Pergameni  [Opera] Omnia, quae extant, in Latinum sermonem convers published in Basel by Hieronymus Froben and Nicolaus Episcopius in 1562, was the first bio-bibliography. Gessner's study, which covered Greek editions, Latin editions, lost works, writers on Galen and a classified bibliography of Galen's writings, was also Gessner's most developed bibliography. The bio-bibliography occupies 37 unnumbered leaves, following the title to volume 1, and Gesner's two unnumbered leaves of dedication, dated February 1562. (α†^4-6,β†⁶, γ†⁶, A†-C†⁶, D†⁴). To the extent that this is a bio-bibliography we might call it an early partial biography, in that it incorporates what little is known of Galen's life.
