The triumphant King, escorted by his troops, the loyal inhabitants and the clergy, proceeded to the mosque. Christian bishops purified the temple, and dedicated it to the service of God and the Virgin, and a high and imposing Mass was celebrated. Amid festivities and ceremonies, Fernando took possession of Seville and all its rich treasure. He occupied the Alcázar, then in its pristine splendour, and divided the houses and land around the city among his knights. The Christian King was brave, and his treatment of the conquered shows that he had a strain of mercy in his nature. He was, however, an intensely bigoted pietist, for at Palencia he set fire with his own hands to the faggots to burn heretics. His austerities were excessive, and fasting is said to have weakened his body. Fernando died from dropsy at Seville, four years after his conquest of the town. On his deathbed he called his son Alfonso, bade him farewell, and exhorted him to follow justice and clemency. Then, amid deep sorrow in the city, the King took the Mass, and passed away. In 1671 Fernando III. was canonised by Pope Clement X. The keys of Seville, which were given up by the Governor at the surrender of the city, may be seen in the cathedral. One key is of silver, and bears the inscription: 'May Allah grant that Islam may rule for ever in this city.' The other key is made of iron-gilt, and is of _Mudéjar_ workmanship. It is lettered: 'The King of Kings will open; the King of the Earth will enter.' San Fernando's shrine is on view in the cathedral on May 30, August 22 and November 23, when honour is paid to the body of the sainted monarch by the soldiers of the Seville garrison, who march past with the colours lowered. In the collection of paintings in the house of Señor Don Joaquin Fernandez Pereyra, 86, Calle Betis, Triana, there is a picture attributed to Velazquez, and said to have been painted by him at the age of twenty-eight, representing the Sultan of Seville handing the keys of the city to San Fernando.[A] It is said that Velazquez painted himself as model of the King. If the work is not that of the master, it is by an artist of parts. The colour is good, and the horse well drawn and painted.
