23 Jul 2020: We publish today AIO Papers 11B, containing images of the five post-Sullan inscriptions honouring ephebes that were the subject of AIO Papers 11. We also publish entries for the two major choregic monuments post-dating the dissolution of the Athenian democracy in 321/0 BC, those of Nikias and of Thrasyllos, and complete the sequence of dedications by agonothetai, IG II3 4, 518 - 539 (IG II3 4, 528 was already on AIO), revising also the notes on the Lysikrates monument (IG II3 4, 460). We have revised the entries for Athens' treaty with the Thracian kings, 357 BC (RO 47) and the treaty with the Thracian, Paionian and Illyrian kings, 356/5 BC (RO 53). AIO now includes updated Greek texts, translations and notes for all the Athenian decrees in RO. We publish the marker of property of the Piraeans, IG II2 2623; and we adjust AIO's entry for the sacrificial calendar of Thorikos (CGRN 32) (ll. 40-41) in the light of the recent update of CGRN. Where up-to-date Greek texts are not available elsewhere online in open access, we have added them in this release to entries first published on AIO in 2017 and 2018, lightly revising the translations and notes. All translations on AIO are now accompanied by a corresponding Greek text either on AIO itself or on a linked open-access site. For a list of new entries published today see Publication 23 July 2020.
