EGUIARA Y EGUREN, Juan Jos6 (aygheeah'rah), Mexican clergyman and author, born in the City of Mexico in the latter part of the 17th century; died there, 29 January 1763. He studied at the College of San Ildefonso, and was afterward canon, professor of theology, and rector of the University of Mexico. His desire to give up his time to his literary tasks made him decline the bishopric of Yucatan, for which he was nominated. He was the author of the first dictionary of biography in South America, which he called "Biblioteca Mexicana," containing the results of much curious research (Mexico, 1765). He printed the first volume of this work, containing the letters A, B, and C, in his own press, and left in manuscript other volumes, which are in the library of the cathedral of Mexico. Among his other works are "Praelecclones" (1726'47); "Selectae disertationes Mexicanae ad Scholasticam speciantes Theologiam" (3 vols., 1746); "La Nada contrapuesta en las balanzas de DiGs al aparente peso de los hombres" (1727); and " Vida del V. P. Pedro Arellano Sosa, primer Preposito de San Felipe Neri" (1735).
