The Daughters of the Cid (1879) by the Spanish painter Ignacio Pinazo y Camarlench (1849-1916).
Legend tells that the daughters of the famous Spanish hero, the Cid, were once expelled by their husbands the princes of Carrión. But there is nothing told of torture, nudeness and so on.
Nevertheless Pinazo y Camarlench used the subject to paint two sweet suffering nude girls during his scholarship in Rome. Interesting is that a generation earlier a painter would have used a classical subject to present his nudes, but now the artist turned more to his own national history, which was invented as well.
