In early April 2013 I had the opportunity to examine stone EM 10300 in the Epigraphical Museum Athens. The inscription, originally from Lamia in the southern periphery of Thessaly, was first published by Stephanos A. KOUMANOUDIS in the Greek periodical Ἐφημερὶς τῶν Φιλομαθῶν 24 October 1864 (No. 541) after a copy made in situ by A. BLASTOS. Two years later the stone had been brought to the National Archaeological Museum in Athens, and P. EUSTRATIADIS made a revised publication of the text in the same periodical, 22 December 1866 (No. 617), based on an autopsy of the stone. Because Ἐφημερὶς τῶν Φιλομαθῶν did not have wide circulation, Basilius LATISCHEW (Vasilii LATYSHEV) re-published the inscription in the Mitteilungen des Deutschen archäologischen Instituts No. 7 1882, along with one other Lamian proxeny decree (now IG IX,2 60), made on the basis of his own autopsy of the stone and provided in his publication an apparatus and minimal commentary on the dating of the inscription. The inscription was last edited in IG IX,2 (1908) by Otto KERN from a squeeze. For the reason that no substantial commentary on this inscription currently exists, and because some relatively recently proposed restorations seem unlikely based on the examination of the actual stone, I present here a new edition of the text with a brief philological commentary.
