[GRASSI, Orazio (1583–1654)] – SARSI, Lothario. Libra astronomica ac philosophica qua Galilaei Galilaei opiniones de cometis [...] examinantur. Perugia: Marco Naccarini, 1619.

Very rare first edition of Grassi’s attack on Galileo’s theory of comets, which had been expressed under his disciple Mario Guiducci's name in his Discorso of 1619. The work provoked the “controversy of the comets” and a wealth of published attacks between the scientists, culminating in Galileo's ll Saggiatore. Carli-Favaro 17 (81); Cinti 139 (64); Riccardi I, 628 (“Raro”).

Quarto (192 × 137mm). Engraved plate of one of the 1618 comets on title-page, woodcuts throughout (spotting, toned). Modern vellum (bowed).
