Luis Ricardo Falero (1851 – December 7, 1896) Duke of Labranzano, was a Spanish painter. He specialized in female nudes and mythological, oriental and fantasy settings. His most common medium was oil on canvas. He studied art, chemistry and mechanical engineering. The experiments that he had to conduct in the latter two were so dangerous, however, that he decided to focus on painting alone. He was a student of Gabriel Ferrier. After Paris, he studied in London, where he eventually settled.
Falero had a particular interest in astronomy and incorporated celestial constellations into many of his works, such as "The Marriage of a Comet" and "Twin Stars". His interest and knowledge of astronomy also led him to illustrate the works of Camille Flammarion.
