Thespis is said to have invented a new kind of tragedy, and to have carried his pieces about in carts, which[ certain strollers], who had their faces besmeared with lees of wine, sang and acted. After him Aeschylus, the inventor of the vizard mask and decent robe, laid the stage over with boards of a tolerable size, and taught to speak in lofty tone, and strut in the buskin. To these succeeded the old comedy, not without considerable praise: but its personal freedom degenerated into excess and violence, worthy to be regulated by law; a law was made accordingly, and the chorus, the right of abusing being taken away, disgracefully became silent.
