Harpagus

Harpagus, also known as Harpagos (Ancient Greek Ἅρπαγος; Akkadian: Arbaku), was a Median general during the 6th century BC, credited by Herodotus as having put Cyrus the Great on the throne through his defection during the Battle of Pasargadae.

Harpagus, reluctant to spill his own royal blood, gave the child (Cyrus) to a shepherd named Mitradates,[2] who raised him as his own son.

When they were ready, he sent a message to Cyrus, hidden in the belly of a hare, informing him that the Medians would mutiny on the field, should he take arms against his grandfather.

He collected together all the camels that had come in the train of his army to carry the provisions and the baggage, and taking off their loads, he mounted riders upon them accoutred as horsemen.

He also was of the race of the Medes, being the man whom the Median king, Astyages, feasted at the unholy banquet, and who lent his aid to place Cyrus upon the throne..."
