Krotos [1]
( 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).
