Gellio Sasceride

Who was Gellio Sasceride?

Gellio Sasceride was a Danish astronomer and doctor. Sasceride worked as an assistant to Tycho Brahe after studying under him. It is believed that the following words were written by Sasceride to Brahe: Quia adhuc aliquid superest spatii, quae sequuntur paucula, sic expetente typographo, subiungi permisi ex literis cuiusdam medicinae Doctoris, Patavii commorantis, ad quendam studiosum Danum.

Sasceride was also friends with Galileo. On December 28, 1592, after Galileo had begun his studies, he wrote a letter to Sasceride with the words Exordium erat splendidum. In 1590, Sasceride had sent to Galileo the only copy of a book until then found in Italy detailing the heliocentric system.

The crater Sasserides on the Moon is named after him. It lies near Tycho, named after Tycho Brahe.
