A Dictionary of Greek and Roman biography and mythology

(Λόγβασις), a citizen of Selga in Pamphylia. When Selga was attacked by Garsyeris, the general of Achaeus, in B. C. 218, Logbasis, as having been guardian to Achaeus's wife Laodice, was deputed by his countrymen to treat with the enemy, and used the opportunity to make a treacherous agreement for the surrender of the city. His design, however, was detected on the very eve of its completion, and his fellow-citizens burst into his house, and slew him, together with his sons and the enemy's soldiers who were secreted there. (Pol. 5.74-76.)
