The devices upon temples were often esteemed as talismans, and supposed to have an hidden and salutary influence, by which the building was preserved. In the temple of Minerva, at Tegea, was some sculpture of Medusa, which the Goddess was said to have given, [601]αναλωτον ες τον παντα κρονον ειναι (την πολιν); _to preserve the city from ever being taken in war_. It was probably from this opinion, that the [602]Athenians had the head of Medusa represented upon the walls of their acropolis: and it was the insigne of many cities, as we may find from antient coins. The notion of the Cyclopes framing the thunder and lightning for Jupiter arose chiefly from the Cyclopians engraving hieroglyphics of this sort upon the temples of the Deity. Hence they were represented as persons, [603]Ὁι Ζηνι βροντην τ' εδοσαν, τευξαν τε κεραυνον. The Poets considered them merely in the capacity of blacksmiths, and condemned them to the anvil. This arose from the chief Cyclopian Deity being called Acmon, and Pyracmon. He was worshipped under the former title in Phrygia; where was a city and district called Acmonia, mentioned by Alexander [604]Polyhistor. The Amazonians paid the like reverence: and there was a sacred grove called Acmonium upon the [605]Thermodon, which was held in great repute. He was by some looked upon as the offspring of heaven; by others worshipped as Ouranus, and Cœlus, the heaven itself; and Acmonides was supposed to have been his [606]son, whom some of the mythologists made the ruling spirit of the earth. Hence Simmias Rhodius introduces Divine Love displaying his influence, and saying, that he produced Acmonides, that mighty monarch of the earth, and at the same time founded the sea. [607]Λευσσε με τον Γας τε βαρυστερνου Ανακτ' Ακμονιδαν, ταν ἁλα θ' ἑδρασαντα. Acmon seems to have been worshipped of old at Tiryns, that antient city of Greece, whose towers were said to have been built by the Cyclopians. For Acmon was the Cyclopian Deity; and is represented by Callimachus as the tutelary God of the place, though the passage has been otherwise interpreted. [608]Τοιος γαρ αει Τιρυνθιος Ακμων Ἑστηκε προ πυλεων. The term has commonly been looked upon as an adjective; and the passage has been rendered Talis Tirynthius indefessus, which is scarce sense. Callimachus was very knowing in mythology, and is here speaking of the Cyclopian God Acmon, whom he makes the θεος προπυλαιος, or guardian Deity of the place. It was the same God, that was afterwards called Hercules, and particularly styled Tirynthius, to whom Callimachus here alludes, under a more antient name.
