Ariodante is an opera seria in three acts by George Frideric Handel. The anonymous Italian libretto was based on a work by Antonio Salvi, which in turn was adapted from Canti 4, 5 and 6 of Ludovico Ariosto's Orlando Furioso. Each act contains opportunities for dance, originally composed for dancer Marie Sallé and her company.

Orlando furioso is an Italian epic poem by Ludovico Ariosto which has exerted a wide influence on later culture. The earliest version appeared in 1516, although the poem was not published in its complete form until 1532. Orlando furioso is a continuation of Matteo Maria Boiardo's unfinished romance Orlando innamorato. In its historical setting and characters, it shares some features with the Old French Chanson de Roland of the eleventh century, which tells of the death of Roland. The story is also a chivalric romance which stemmed from a tradition beginning in the late Middle Ages and continuing in popularity in the 16th century and well into the 17th.
