"an Archaic-period testimony from Thermos, in Aetolia, where the didascalia of a terracotta image of Iris ( LIMC , sv . Iris I 4), a fragment of a metope from the temple of Apollo ( 7th - 6th centuries BC ), presents the form F ΙΡΙΣ." -Cultes d’Iris en Grèce ancienne : un état de la question (Note 36)
"Thermos. Located on a mountain plateau above the NE end of Lake Trichonis, 34 km from Agrinion, near the modern village of Kephalovryso, the site was settled in the Late Bronze Age. Described as place or topos (Polyb. 5.7.8), the Classical site was the center of Aitolian worship and the meeting place of the Aitolian League, where annual magistrates were elected and large market fairs held (Polyb. 58.4ff)... Nearby to the E is a smaller temple, a small rectangular cella with double colonnade across the S facade, identified by an inscription found nearby as that of Apollo Lyseios. Painted terracotta metopes found within the temple with representations of the Charites, Iris, and the Centaur Polos, may belong to its original construction in the late 7th c." -The Princeton Encyclopedia of Classical Sites via Perseus
