Florisel of Niquea is a Spanish Chivalric romance of the sixteenth century, tenth in the series of Amadís de Gaula, and continues the action.
Its full title is 'The Chronicle of the Very Brave and Hard-working and Invincible Knights Don Florisel de Niquea and the Strong Anaxartes, sons of the very excellent Prince Amadís of Greece'.
The twins Anaxartes and Alastraxerea, sons of Queen Zahara of the Caucasus, who believe they are children of the god Mars but whose real father is Amadís of Greece, are armed knights and set out in search of adventure.
Florisel de Niquea falls in love with Elena, daughter of King Brimartes of Apollonia ( Poland ), fiancée of Prince Lucidor of France.
Alastraxerea, still under the identity of Florisel, is kidnapped by Don Falanges de Astra, extramarital son of the King of Trapobana, who has fallen in love with her.
Prince Lucidor, seized with anger, swears revenge on the Greek imperial house and a war breaks out between France and Greece.
After the war, Amadís of Greece feels his old love for Princess Lucela reborn and he retires to an uninhabited mountain, where he is the victim of an enchantment.
In the course of this search, and to save Don Falanges de Astra from death, Florisel is forced to marry, under the feigned identity of Morayzel, the beautiful Sidonia, queen of the Guindaya island.
At the end of the play, the main characters congregate in Rhodes, where, through the intervention of Zirfea, Alquife and 'Urganda the Unknown', Amadís of Greece recognizes Anaxartes and Alastraxerea as children.
The work presents the peculiarity, very rare in the chivalric genre, of beginning with its chronological location, since as it is said in the first lines of chapter I of the first book, Queen Zahara gave birth to twins Anaxartes and Alastraxerea in May of the year 115 AD.
Florisel de Niquea was a significantly popular work among readers of chivalric books, as it had at least six reprints: three in Seville (one in 1536 and two in 1546 ), one in Lisbon ( 1566 ) and two in Zaragoza ( 1584 and 1587 ).
Mambrino Roseo wrote in Italian a continuation of Silves de la Selva, the First part of Esferamundi of Greece, first published in Venice in 1558.
