Coactor
Coactor This name was applied to collectors of various sorts, e. g. to the servants of the publicani or farmers of the taxes, who collected the revenues for them (Cic. pro Rab. Post. 11, § 30); also to those who collected the money from the purchasers of things sold at a public auction (Id. pro Cluent. 64.180). The father of Horace was a coactor, but there are no means for determining to which class he belonged. (Hor. Sat. 1.6, 86; Suet. Vit. Hor.)
