Outside the Chapel of Sant Iago are more huge heraldic devices: knights in full armor and lions lifting by razor-strops, as if in some test of strength, great wheels encircling crosses. Above them, gargoyles leer demoniacally over the heads of devout cherubim. In the little street of Diego Porcello, named for the great noble who still protects his city from the gate of Santa Maria, nothing can be seen of the great church but bare walls separated from the adjacent houses by a dozen feet of dirty cobblestones. Ribs of the original chapels that once flanked the eastern end, behind the present chapels of Sant Iago and Santa Catarina, have been broken off flat against the exterior walls, and the cusps of the lower arches have been closed. Thus the fabric has been added to, altered, mutilated or embellished by foreign masters as well as Spanish hands. Who they all were, when and why they wrought, is not easy to discover. Enrique, Juan Perez, Pedro Sanchez, Juan Sanchez de Molina, Martin Fernandez, Juan and Francisco de Colonia and Juan de Vallejo, all did their part in the attempt to make Santa Maria of Burgos the loveliest church of Spain. The mighty western façade rises in a confined square where acacia trees lift their fresh, luxuriant heads above the dust. The symmetry of the towers, the general proportions of the mass, the subdivisions and relationship of the stories, the conception as a whole, clearly show that it belongs to an age of triumph and genius, in spite of the disfigurements of later vandals, as well as essentially foreign masters. It is of queenly presence, a queen in her wedding robes with jewels all over her raiment, the costliest of Spanish lace veiling her form and descending from her head, covered with its costly diadem. North and south the towers are very similar and practically of equal height, giving a happily balanced and uniform general appearance. The lowest stage, containing the three doorways leading respectively into north aisle, nave, and south aisle, has been horribly denuded and disfigured by the barbarous eighteenth century, which boasted so much and created so little. It removed the glorious, early portico, leaving only bare blocks of masonry shorn of sculpture. No greater wrong could have been done the church. In the tympanum above the southern door, the vandals mercifully left a Coronation of the Virgin, and in the northern one, the Conception, while in the piers, between these and the central opening, four solitary statues of the two kings, Alfonso VI and Saint Ferdinand, and the two bishops, Maurice and Asterio, are all that remain of the early glories. The central door is called the Doorway of Pardon.
