Greek poet, probably of the Aegean island of Cos, author of mimes—short dramatic scenes in verse of a world of low life similar to that portrayed in the New Comedy. His work was discovered in a papyrus in 1890 and is the largest collection of the genre. It is written in rough iambic metre and in the vigorous, rather earthy language of the common people. His characters use vehement exclamations, emphatic turns of speech, and proverbs.

In pieces of about 100 lines Herodas portrays vivid and entertaining scenes with the characters clearly drawn. The themes cover a range of city life: a procuress attempts to arrange a tryst for a respectable matron while her husband is away; a jealous woman accuses her favourite slave of infidelity and has him bound and sent to receive 2,000 lashes; a desperate mother drags a truant urchin to the schoolmaster. It is thought that these mimes were recited with considerable improvisation by an actor who took the various roles.
