Periaktos
(重定向自Periaktoi)

Periaktos (plural form Periaktoi, from Greek revolving) is a device used for displaying and rapidly changing theatre scenes. It was first mentioned in Vitruvius' book on architecture, De architectura (c. 14 BC) but its most intense use began in Renaissance theatre, as a result of the work of important theatrical designers, such as Nicola Sabbatini (1574-1654).
