 Telchines were regarded as excellent metallurgists; various accounts state that they were skilled metal workers in brass and iron and made a trident for Poseidon and a sickle for Cronus, both ceremonial weapons.Together with their help and the Cyclopes, the smith god Hephaestus forged the cursed necklace of Harmonia.Because of their excellent workmanship, the Telchines were maligned by rival workmen and thus received their bad reputation.
