Pietro Pitati

Bernardino Baldi, in his Cronica de matematici (1707) calls Pitati a noble Veronese who was trained in mathematics by a Benedictine friar named Innocentio da Novara.

De varia paschalis solemnitatis obseruatione...De Hebraica anni quantitate...Calendarium nouum cum noua aurei numeri positione, ortu quoque, & occasu stellarum fixarum (Venice, March 1537) is one of many sixteenth century attempts to reform the calendar, and establish, among other things, the correct day of Easter.

[2] Pitati also wrote another book bearing on the length of the solar and lunar year, the fixed stars, and calendar reform, entitled: Compendium .

super annua solaris atque lunaris anni quantitate Paschalis item solennitatis juxta veteres ecclesiae canones recognitione Romanique calendarii instauratione deque vero Passionis Dominicae die ortu quoque et occasu stellarum fixarum, in tres divisum Tractatus.

Isagogica in coelestem Astronomicam disciplinam ... Tractatus tres perbreues de Electionibus, Reuolutionibus annorum, & mutatione aeris.
