Who is Sosigenes of Alexandria?

Sosigenes of Alexandria was named by Pliny the Elder as the astronomer consulted by Julius Caesar for the design of the Julian calendar.

Little is known about him apart from Pliny's Natural History. Sosigenes appears in Book 18, 210-212:

In Book 2, chapter 6, Sosigenes is credited with work on the orbit of Mercury:

Some sources state that the Julian calendar was designed by Aristarchus of Samos; it is not clear where this originates, although a reform of the Egyptian calendar was decreed by Ptolemy III Euergetes in 238 BC, but never implemented.

Sosigenes was portrayed by Hume Cronyn in the 1963 movie Cleopatra.
