Only a little over two months of this calendar have been preserved, but they contain several events in honour of various kings. The inscription has plausibly been to the period when Attalos II was king of Pergamon, and Ptolemy VI was king of Egypt.
There is a French translation and commentary by B. Le Guen-Pollet, "La vie religieuse dans le monde grec du Ve au IIIe siècle avant notre ère", p. 196, no. 65 ( Google Books ); and a discussion in English by K. Höghammar, "The sanctuary of the Twelve Gods in Kos and the stelai with proxeny decrees", pp.85-87 ( PDF ).
