Christians found their own, which had collected together in white balls or masses, separate from the rest. In 1389, the regular canons, to whom the church belonged, resolved to rebuild a part of it: in digging the foundation, two marble chests were discovered. The lid of the smaller was fastened down very firmly with a sort of pitch; when this was taken off, two sets of human bones were found in different compartments; over the one were the words _Lupercii Martyris_, sculptured in the marble; over the other, _Engratiæ Virginis_: these latter were of rose-colour, which was admitted as proof of their authenticity. The larger chest contained a great assortment of anonymous bones, ashes, and the white masses, which had disappeared for so many centuries. The mine was very rich; the workmen went on till they had invented thirteen chests, and at last, a whole pit full of relics, not the less efficacious because it could not be ascertained to whom they had belonged. Seventy years afterwards, Juan II. of Aragon, one of the wickedest and most perfidious of men, fancied or feigned, that by St. Engracia’s intercession, he was cured of a complaint in his eyes; in consequence of which, he resolved to enlarge this church, and build a monastery adjoining it for the Jeronimites, ... an order which, during that and the succeeding age, was in great favour at the three courts of the Peninsula. He began his work, but died without completing it, leaving that charge by will to his son, Ferdinand, the Catholic king. He continued the building, but it was not finished till the reign of Charles the Fifth.
