There are several paintings here by the genial Pacheco, the father-in-law of Velasquez; among others one of St. Peter Nolasco, the tutor of Don Jayme _el Conquistador_, going in a boat to the redemption of captives. The man at the prow is Cervantes, who, with the other _beaux esprits_ of the day, used to assemble in the studio of Pacheco, a man of erudition and a poet as well as a painter. Pacheco was a familiar of the Inquisition, and inspector of sacred pictures. It was in the latter capacity he laid down rules for their representation, among which were some relating to paintings of the Immaculate Conception (he has two paintings of this subject in the museum), which were generally adhered to in Spain. The general idea was taken from the woman in the Apocalypse, clothed with the sun, having the moon under her feet, and upon her head a crown of twelve stars. The Virgin was to be represented in the freshness of maidenhood, with grave, sweet eyes, golden hair, in a robe of spotless white and a blue mantle. Blue and white are the traditional colors of the Virgin. In the unchanging East Lamartine found the women of Nazareth clad in a loose white garment that fell around them in long, graceful folds, over which was a blue tunic confined at the waist by a girdle――a dress he thought might have come down from the time of the patriarchs. But to return to Pacheco. It was he who, in the seventeenth century, took so active a part in the discussion whether St. Teresa, just canonized, should be chosen as the _Compatrona_ of Spain. Many maintained that St. James should continue to be considered the sole patron, and Quevedo espoused his cause so warmly that he ended by challenging his adversaries to a combat _en champ clos_, and was in danger of losing his estates. Pacheco, as seen by existing manuscripts, wrote a learned theological treatise against him, taking up the cause of St. Teresa, which proved victorious. She was declared the second patron of Spain by Philip III.――a decision re-echoed by the Spanish Cortes as late as 1812. All the prominent men of the day took part in this discussion, even artists and literary men, as well as politicians and the clergy.
