Sirigatti translated the "Liber astronomiae" by Guido Bonatti and Lugio Bellantis' "Tractatus astronomiae" and dedicated his work to the Medici Pope Leo
Traces of worms, the layers H-I (16 sheets) in the lower margin slightly shorter, as is often the case without 4 sheets (preface, frontispiece, dedication sheet and epigram) at the beginning , partly more browned in places, otherwise in good condition.
Text in Latin
Sirigatto, a Florentine working before 1550, initially published this work in Naples in 1531 ("Fort rare" Huzeau & Lancaster).
Using the Ptolemaic system of celestial motion, Sirigatto here lays out his own observations of the appearance and the various movements of the constellations throughout the year. The work is divided into two 'books', the first dealing with a day-by-day annual account of the appearance of the constellations, the second describing their movements in 'rising' and 'setting' ('ortu' and 'occasu'), this data theoretically permitting the contemporary scientist to predict the motion of the stars.
