Tras considerar el proceso de recepción de las poesías de Pedro de Quirós, a partir del manuscrito hispalense, publicado con estudio de Menéndez Pelayo en 1887, se da a conocer un nuevo y más completo códice rotulado Rimas de Doripso de Quer (Ms. 8494 de la B. N. M.). Se estudia la relación entre ambos manuscritos presentando las composiciones hasta ahora desconocidas y que se publican como apéndice final.After dealing with the the process of critical recepction undergone by Pedro de Quirós´s poems, through the so-called "manuscrito hispalense" (which was published in 1887 with a study by Menéndez Pelayo), this paper makes know a new and fuller manuscript entitled Rimas de Doripso de Quer (Ms. 8494 of the Spanish National Library-B.N.C.).
