In 305 BC the Ptolemaic Kingdom was founded in Egypt by the Greeks.

As a result, the name Hermes Trismegistus started being used to describe  the god who was both Thoth and Hermes. You can read more about the combining of the two deities here.

The Greeks recognized Thoth as being the Egyptian version of their god Hermes.
