DIVINI, Eustachio (1610-1685). Brevis annotatio in Systema Saturnium Christiani Hugenii. Rome: J. Dragondelli, 1660.
8° (191 x 125mm). Folding engraved plate, woodcut device on title, initial, ornamental typographic headpiece. (B6 with short tear due to paper flaw, just into text and affecting a couple of words, C8 with repaired tear just into text affecting a couple of letters, folding plate with some light creasing, occasional light staining mostly confined to margins.) Modern boards, uncut.
RARE FIRST EDITION OF DIVINI'S ATTACK ON HUYGENS. Huygens discovery in 1665 of the satellite of Saturn, later called Titan, and his proposal that the 'arms' of Saturn were in fact a single ring, were not widely accepted, and a pamphlet war started. By 1670, Huygens had won the day, and the Saturn ring theory was mostly accepted.
