Is Easter based on a pagan tradition?

[Minimalist]

There is no historical mention of anyone by that name.

Certainly not among the Diadochi who battled for control of Alex's Empire after his death which would be the context I would expect to find him. This is all I can come up with on it.

THE CITY OF CAESAREA, or as it was frequently called Caesarea of Israel, was situated on the coast of the Mediterranean between Joppa and Tyre. The site was occupied originally by an ancient village called the Tower of Strato. Herod the Great built here a magnificent and Strongly fortified city, which he named Caesarea, in honor of Augustus. He formed a secure harbor by constructing a vast breakwater out into the sea. Caesarea was the capital of Judea during the reigns of Herod the Great and Agrippa I., and was the usual residence of the Roman Governor, when Judea became a mere province of the Empire. The inhabitants were principally Greeks. - Ancient Geography

I do however have Caesar being pissed at Ptolemy for killing a Roman even if one Caesar would have killed had he gotten to him first.

But Ptolemy did not kill Antony. Antony committed suicide after Octavian landed in Egypt. Ptolemy XIII did murder Pompey but Julius Caesar dealt with him some years prior. So, that one remains a mystery.
