Charles B. Curtis. Velazquez and Murillo. London, 1883, pp. 300–1, no. 476i, lists as no. 476i a portrait of "Pedro Nuñes de Villavicencio, Knight of the Military Order, friend, pupil and protector of Murillo (b. 1644, d. 1700)" and states that it was sold in London June 12, 1874 to Palmer for £178.10s; notes that Julian Williams "had recently a full-length portrait of Villavicencio".
Catalogues of Pictures by Old Masters. Christie's, London. February 10, 1912, p. 6, no. 18, notes in error that the sitter wears the "Riband and Order of Saint John of Jerusalem"; as formerly in the collection of Count de Benomar.
August L. Mayer. Murillo: Des Meisters Gemälde. Stuttgart, 1923, pp. 226, 293 [see Ref. Angulo Íniguez 1981, p. 331], dates it about 1645–50; observes that the sitter cannot be Pedro Nuñez de Villavincencio as he was a Knight of Malta only and that his life dates (1644–1700) do not coincide with the supposed age of the sitter in the portrait.
Georg Jacob Wolf. "Munich." Art News 26 (February 18, 1928), pp. 16–17, ill., dates it to about 1650; calls it the high point among works shown at E. A. Fleischmann's Gallery, Munich.

Diego Angulo Íñiguez. Murillo. Madrid, 1981, vol. 2, pp. 331–32, no. 422; vol. 3, pl. 457, as "Knight of Alcántara," possibly a relative of Pedro Nuñez de Villavicencio; dates it about 1650–60 and catalogues it with autograph works, noting, nevertheless, that it may be the work of a follower; contributes to the provenance, and observes that the picture described in the 1912 sale may be identical with ours and the medal and ribbon incorrectly identified.
