What is "aryandes"

Aryandes was the Persian satrap of Egypt in the late sixth century BCE. He was first appointed in c. 525 BCE by Cambyses, the Persian conqueror of Egypt. In 521 BCE, Aryandes probably dealt with a rebellion led by a local dynast named Petubastis. By 497 BCE, Aryandes had fallen out with the reigning Persian monarch, Darius I, and was executed for treason.
