What is "banausos"

Banausos ( Ancient Greek , plural , banausoi) is an epithet of the class of manual laborers or artisans in Ancient Greece. The related abstract noun – banausia is defined by Hesychius as "every craft [conducted] by means of fire", reflecting the folk etymology of the word as coming from (baunos) "furnace" and (auō) "to dry". The actual etymology of the words is unknown; they are not attested outside Attic- Ionic or before the 5th Century BC. The epic heroes call their smiths – dēmiourgoi.
