Krotos

Krotos (κρότος), a word used to signify approbation of a public speaker. It means literally a beating, striking, knocking, as of the hands, together; and hence it was used to signify consent and approbation, either by words or actions. Public applauses and acclamations appear to have been common in the early Church.-Farrar, Eccl. Dict. SEE ACCLAMATIONS.
