It is generally believed that a substantial number of time intervals and traditional dates given for early Greek history are the result of calculations based on genealogies and on various values for a generation. Although this method is supposed to have been used by Greek chronographers from the fifth century down at least to Kastor of Rhodes in the first, Herodotos must be our main direct evidence.

In the much discussed list of thalassocrats excerpted by Eusebios from Diodorosthe tenth entry remains the most puzzling.2 Although the name is missing inEusebios' Chronographia, both the Armenianversion of the Canons and Jerome's Latin Canons give this place to the Karians, and the Armenian Canons are generally followed for the period of rule of sixtyoneyears:3 ‘Zehntens führten die Seeherrschaft die Karier, 61 Jahre.’ The years apparently covered by this Karian thalassocracy are c. 735–674 B.C.4.
