Pier Candido Decembrio

Eight-leaf Roman incunable of Decembrio's astrological treatise 'De genitura hominis' on how the stars govern human conception and birth, printed by Stephan Plannck not after 1487. A short fifteenth-century pamphlet (8 leaves), the kind of thin printing that rarely survives in numbers. Digitized by the U.S. National Library of Medicine (public domain).
