Orazio Grassi
Orazio Grassi (born May 1, 1583 in Savona , † July 23, 1654 in Rome ) was a Jesuit , Italian mathematician , astronomer and architect . Grassi was a contemporary of Galileo Galileo , with whom he exchanged information about the nature of comets in pamphlets . In 1619 his treatise Libra astronomica et philosophica appeared under the pseudonym Lotario Sarsi Sölkerano, in which he attacked Galileo. Galileo replied in 1623 with his Il Saggiatore . Pietro Redondi saw in this dispute the real origin for the later trial against Galileo, but this is disputed by most historians.
Grassi studied mathematics and theology from 1600 in Rome at the Jesuit college Sant'Andrea al Quirinale , among others with Christophorus Clavius , Christoph Grienberger and Odo van Maelcote . After completing his studies in 1610, he was sent to the Jesuit College in Genoa as the novice chaplain in 1614 and in 1616 he became a mathematics professor at the Collegio Romano in Rome, which he remained until 1628. In addition to lectures on geometry and astronomy, he also gave lectures on optics (published in 1617 as De iride disputate optica , under the name Galeazzo Mariscotto) and architecture. As an architect, he designed the church of Sant Ignazio next to the Collegio Romano.
Manuscripts of him are also known, Tractatus tres de sphera, de horologis ac de opticae from 1617 and a treatise on the sundials in Vitruvius ( In primum librum de architectura M. Vitruvii et in nonum eiusdem De horologiorum solarium descriptione duo brevissimi tractati ) from 1624 .
