The Greeks of Cyrenaica seemed also to have adopted some Berber customs and intermarried with the Berber women. Herodotus (Book IV 120) reported that the Libyans taught the Greeks how to yoke four horses to a chariot( Romans will use these Lybian chariots later, but through Greek taught). The Cyrenaican Greeks built temples for the Libyan god Ammon instead of their original god Zeus. They later identified their supreme god Zeus with the Libyan Ammon. Some of them continued worshipping Ammon himself.
