Forms

foculus m (genitive foculī); second declension[1] Plautus has a neuter plural focula.[2]

Etymology

It is from Latin focus (“hearth”) + -ulus.[3][1][2] De Vaan finds no acceptable etymology for focus; he rejects Hamp's view that focus was formed back from this diminutive as chronologically difficult.[4]

Earliest recorded meaning

Plautus speaks of dishes kept warm on glowing braziers, epulas foveri foculis ferventibus,[2] and jokes about leftovers warmed on the brazier of the belly.[2] De Vaan and Köbler date it from Cato,[4][5] who has it of a small coal pan for warming.[6]

Semantic evolution

It is a small portable stove or brazier, especially one used at sacrifices.[3] Varro, Cicero and Seneca use it of a small sacrificial hearth, and Livy of a man thrusting his right hand into a fire lit for sacrifice.[6][2] Pliny the Elder tells of a likeness drawn on a wall with a dead coal snatched from a brazier.[2] Juvenal uses it for the fire itself, blown up with puffed cheeks.[2][6] Church Latin has it as a portable stove or chafing dish.[7]
