Innovative as it is, Luis Valdez' acto owes much to the theater traditions or(我认为应为 of，印刷错误) other periods and regions. Like early Spanish American religious dramas, secular folk dramas, and the Mexican carpas of a somewhat later period, actos are usually performed outdoors by traveling groups of players or by local theater groups. The improvised comic satire of the actos is often attributed to Valdez' study of the Italian commedia dell' arte of the sixteenth century, although some critics see it as a direct reflection of the comic and improvisational qualities of the more contemporary and local carpas of Mexican theater. The Italian influence is likely, whatever Valdez‘ immediate source: the Mexican carpas themselves are said to have originated from the theater pieces of a sixteenth-century Spanish writer inspired by encounters with Italian commedia dell'arte troupes on tour in Spain.
