Saenu[…] issued inscribed coinage in c.45AD contemporary with those of his Icenian rival kings Anted[ios], who was nominal king over all the Iceni in the eyes of Rome, and Aesu[…], who, like Saenu[..] possibly resented the preferential treatment that Anted[ios] was afforded by Rome. He was presumably one of the leading lights during the Icenian War of 47AD and was in all likelyhood killed either during the fighting or in retribution by Rome immediately afterwards.
