Meaning of lotario by Gervasio

Lotario is a character in a short novel entitled A Curious Impertinent of the same style as the Exemplary Novels, interspersed by Miguel de Cervantes in the first part of Don Quixote. The story is set in Florence, and concerns two friends named Lothair and Anselm, and his wife, Camila. Anselmo, prey to an impertinent curiosity, asks Lotario to court Camila, to find out if she is faithful to him. At first, Camila indignantly rejects Lothair's claims, and Anselm is very pleased with his wife's fidelity, but decides to let Lothair insist. At last, Lotario and Camila become lovers, while Anselmo remains convinced of their loyalty. An unforeseen circumstance causes, however, that the whole truth is discovered, Camila flees from her house, and Anselmo dies of sorrow at the time of writing the cause of his death. In the Anglo-Saxon world and in the English language, the cervantino character, under the Britishized form Lothario, has come to constitute an eponym, so that in English, Lothario serves to designate the selfish and unscrupulous seducer. The term became popular through nicholas rowe's 1703 work "The Fair Penitent" by Nicholas Rowe, 2? one of several English derivations of Cervantes' work.
