On the whole, modern authorities assign Pheidon to the first half of the 7th century. According to Konrad H. Kinzl, Pheidon can be dated in the middle of the sixth century BCE.. Pheidon is said to have lost his life in a faction fight at Corinth. which was under the rule of Cypselus, where the monarchy had recently been overthrown. It is unknown with which faction he had sided. Herodotus further states that Pheidon established a system of weights and measures throughout the Peloponnesus, to which Ephorus and the Parian Chronicle add that he was the first to coin silver money, and that his mint was at Aegina. But according to the better authority of Herodotus (i. 94) and Xenophanes of Colophon, the Lydians were the first coiners of money at the beginning of the 7th century, and, further, the oldest known Aeginetan coins are of later date than Pheidon. Hence, unless a later Pheidon is assumed, the statement of Ephorus must be considered unhistorical. No such difficulty occurs in regard to the weights and measures; it is generally agreed that a system was already in existence in the time of Pheidon, into which he introduced certain changes. A passage in the Aristotelian Constitution of Athens states that the measures used before the Solonian period of reform were called Pheidonian..
