Abul-Abbas was an Asian elephant brought back to Carolingian emperor Charlemagne by his diplomat Isaac the Jew.

However, no references to the gift or to interactions with Charlemagne have been found in Abbasid records.

Alcina is an opera seria by George Frideric Handel. Handel used the libretto of L'isola di Alcina, an opera that was set in 1728 in Rome by Riccardo Broschi, which he acquired the year after during his travels in Italy.

The opera contains several musical sequences with opportunity for dance: these were composed for dancer Marie Sallé.

The chanson de geste is a medieval narrative, a type of epic poem that appears at the dawn of French literature. The earliest known poems of this genre date from the late eleventh and early twelfth centuries, before the emergence of the lyric poetry of the trouvères (troubadours) and the earliest verse romances. They reached their highest point of acceptance in the period 1150–1250.

Charlemagne or Charles the Great, numbered Charles I, was the King of the Franks from 768, the King of the Lombards from 774, and the Emperor of the Romans from 800. During the Early Middle Ages, he united the majority of western and central Europe. He was the first recognised emperor to rule from western Europe since the fall of the Western Roman Empire around three centuries earlier. The expanded Frankish state that Charlemagne founded is called the Carolingian Empire. He was later canonised by Antipope Paschal III.

Its composition dates anywhere from the end of the twelfth century to the middle of the fourteenth century. Five versions of the tale are extant, dating from the fifteenth century to the sixteenth century, one in verse and the others in prose.

Morgan le Fay, alternatively known as Morgan[n]a, Morgain[a/e], Morg[a]ne, Morgant[e], Morge[i]n, and Morgue[in] among other names and spellings, is a powerful enchantress in the Arthurian legend. Early appearances of Morgan do not elaborate her character beyond her role as a goddess, a fay, a witch, or a sorceress, generally benevolent and related to King Arthur as his magical saviour and protector. Her prominence increased over time, as did her moral ambivalence, and in some texts there is an evolutionary transformation of her to an antagonist, particularly as portrayed in cyclical prose such as the Lancelot-Grail and the Post-Vulgate Cycle. A significant aspect in many of Morgan's medieval and later iterations is the unpredictable duality of her nature, with potential for both good and evil.

Orlando finto pazzo is an opera in three acts composed by Antonio Vivaldi to a libretto by Grazio Braccioli. The plot is based on an episode in Matteo Boiardo's unfinished epic poem Orlando Innamorato. The second of Vivaldi's known operas, Orlando finto pazzo premiered in November 1714 at the Teatro Sant'Angelo in Venice. Vivaldi acted as impresario as well as composer. Apparently the opera did not meet much approval from the audience and was billed only on few dates, just to be replaced, on 1 December, by a reworking of Giovanni Alberto Ristori’s Orlando furioso, an opera that the Vivaldi "impresa" had very successfully staged in 1713.

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.

Orlando, usually known in modern times as Orlando furioso, is an opera in three acts by Antonio Vivaldi to an Italian libretto by Grazio Braccioli, based on Ludovico Ariosto's epic poem Orlando Furioso. The first performance of the opera was at the Teatro San Angelo, Venice, in November 1727. It is to be distinguished from an earlier Vivaldi opera of 1714, Orlando furioso, set to much the same libretto, once thought to be a revival of a 1713 opera by Giovanni Alberto Ristori but now considered by Vivaldian musicologists to be a fully-fledged opera by Vivaldi himself.

The paladins are twelve fictional knights of legend, the foremost members of Charlemagne's court in the 8th century. They first appear in the mediaeval chanson de geste cycle of the Matter of France, where they play a similar role to the Knights of the Round Table in Arthurian romance. In these romantic portrayals, the chivalric paladins represent Christianity against a Saracen (Muslim) invasion of Europe. The names of the paladins vary between sources, but there are always twelve of them led by Roland. The paladins' most influential appearance is in The Song of Roland, written between 1050 and 1115, which narrates the heroic death of Roland at the Battle of Roncevaux Pass.

In remorse, Rodomonte builds a bridge in her memory and forces all who cross it to pay tribute. When the "naked and mad" Orlando arrives at the bridge, it is Rodomonte, the pagan, who throws him into the river below. They both swim ashore, but Orlando who is naked and is unimpeded by heavy armors get to the shore first. Finally, Rodomonte appears at the wedding of Bradamante and Ruggiero and accuses Ruggiero of treason for converting to Christianity and abandoning the Saracen cause. The two fight a duel and Rodomonte is killed.

Roland was a Frankish military leader under Charlemagne who became one of the principal figures in the literary cycle known as the Matter of France. The historical Roland was military governor of the Breton March, responsible for defending Francia's frontier against the Bretons.
