Ptolemy

This name isn't quite as ancient as it used to be. Ptolemy Tompkkins, son of the "New Age" author Peter Tompkins, is now a fairly well-known author in his own right. And in October 2007 the American actress Gretchen Mol and her husband Kip Williams named their son Ptolemy.

Ptolemy was a name used by many Egyptain kings. It is also the name of a character in Jonathan Stroud's Bartimaeus series (the third book is even named Ptolemy's Gate after him).
