The reconstructions of the Orthagoras genealogy are so numerous and so different that it is rarely used for chronological purposes. The aim of this paper is to show that there is clear evidence on this subject, and that it has chronological value.

The introduction of the trireme into Greek navies was an event of great political importance, which may fairly be compared to the introduction of the ‘all-big-gun’ battleship into the British Navy in 1907. Heavier, more powerful, and capable of carrying more πιβται, but making greater demands on timber supplies and manpower, the trireme not only rendered obsolete all existing Greek line-of-battle ships but gave a decisive advantage to those States whose resources in materials and men enabled them to create and (...) maintain adequate fleets of the new type of warship.1 It is a mark of the insufficiency of our sources for early Greek history that we nowhere find an explicit statement of the date at which this revolution occurred, or of the identity of the person responsible.
