"Della fede Christiana santo atleta, Benigno a' suoi, et a' nemici crudo-- --E negli sterpi eretici percosse L'impeto suo più vivamente quivi Dove le resistenze eran più grosse." --PARADISO, XII. Born at Calaruega, in Old Castile, in 1170, of a stock which his brethren love to connect with the royal house, his saintliness was so penetrating that it reflected back upon his mother, who is reverenced as St. Juana de Aga, and at one time there was danger that even his father might be drawn into the saintly circle. Both parents were buried in the convent of San Pedro de Gumiel, until, about 1320, the Infante Juan Manuel of Castile obtained the body of Juana to enrich the Dominican convent of San Pablo de Peñafiel which he had founded; when Fray Geronymo Orozco, the Abbot of Gumiel, prudently transferred the remains of Don Felix de Guzman to an unknown spot in order to preserve it from an extension of acquisitive veneration. Even the font of white stone, fashioned like a shell, in which Dominic was baptized could not escape. In 1605 Philip III. transported it with much pomp from Calaruega to Valladolid. Thence it was translated to the royal Convent of San Domingo in Madrid, where it has since been used for the baptism of the royal children.[217] Ten years of training in the University of Palencia made of Dominic an accomplished theologian and equipped him thoroughly for the missionary work to which his life was devoted. Entering the Chapter of Osma, he was speedily made sub-prior, and in this capacity we have seen him accompany his bishop, who from 1203 onward for some years was employed on missions that carried him through Languedoc. Dominic's biographers relate that his career was determined by an incident in this first voyage, when he chanced to lodge in the house of a heretic of Toulouse and spent the night in converting him. This success, and the sight of the wide extent of heresy, led him to devote his life to its extirpation. When in 1206 Bishop Diego dismissed his retinue and remained to evangelize the land, Dominic alone was retained; when Diego returned to Spain to die, Dominic remained behind and continued to make Languedoc the scene of his activity.[218]
