[1] Some have identified the town as the Chaetae (Χαῖται) – "Κλ" being mistaken for "Χα" – in Ptolemy.
[2] In the Delphic Theorodochoi inscription (230 BC), published by André Plassart, there is a mention of a man who was named Phaneas Solonos (Ancient Greek: Φανέας Σόλωνος) from Clitae.
[3] Clitae is mentioned by Pliny the Elder as a centre of natron production from the ancient lake Chalastra (Ancient Greek: Χαλάστρα), which is identified as the salt lake now known as Pikrolimni.
[4][5][6] The chalestraion nitron (Ancient Greek: χαλεστραῖον [νίτρον]) produced in Clitae and used in Graeco-Roman glassmaking is mentioned by Plato in the Republic (430a) and praised for its high quality by Pliny.
[4] Combined with the identification of lake Chalastra with Pikrolimni and glassware found in the vicinity, the ruins of Clitae are considered to lie in a site near the modern village Xylokeratia of Kilkis prefecture, Greece.
