See José Simón Díaz, Bibliografía de la literatura hispánica, 2nd ed., Vol. III, Part 2 (Madrid: C.S.I.C., 1965), 437-524, and the present author’s «Más datos bibliográficos sobre libros de caballerías españoles», Revista de Literatura, 34 (1968 [1970]), 5-14. (This information is presented in a somewhat updated form as an Appendix to the Bibliography of the present author’s Ph. D. thesis, «An Edition of a Sixteenth-Century Romance of Chivalry: Diego Ortúñez de Calahorra’s Espejo de principes y cavalleros [El Caballero del Febo]», Diss. Brown University 1971 [1970]. Also included on p. xxix, n. 35 and on p. cii, n. 1 are lists of errors and misprints in the cited section of Simón Díaz’s work.) Of the known Spanish romances of chivalry (and there are likely a few we do not know about, as well as several works, known only by title, of which it is not certain whether they are chivalric or not), we know the location of some version of the text for all the works except the following: Leoneo de Hungría and Lucidante de Tracia, known only through Fernando Colón’s catalogue, and Leonís de Grecia, known from another sixteenth century book inventory, all of which may be lost forever, and Lidamante de Armenia, which Sir Thomas Phillipps had a manuscript of and Clemencín saw an edition of. Thanks to the assistance of my former colleague Juan Bautista Avalle Arce, the missing Philesbián de Candaria has been located (see the article cited in n. 4).
