In front of the High Altar at the feast of Corpus Christi and on three other occasions, the _Seises's_ dance takes place. This strange ceremony is performed by chorister boys who dance a sort of minuet with castanets. Their costume is of the time of Philip III., _i.e._, 1630, and they wear plumed hats. Of the numerous chapels the most interesting is the Capilla Real. It possesses a staff of clergy all to itself. Begun in 1514 by Martin de Gainza, it was finished fifty years later. Over the High Altar is the almost life-size figure of the Virgin de los Reyes, given by St. Louis of France to San Ferdinand. Its hair is of spun gold and its numerous vestments are marvellous examples of early embroidery. The throne on which the Virgin is seated is a thirteenth-century piece of silver work, with the arms of Castile and Leon, San Ferdinand's two kingdoms. Before it lies the King himself in a silver shrine. Three times a year, in May, August and November, a great military Mass takes place before this royal shrine, when the garrison of Seville marches through the chapel and colours are lowered in front of the altar. In the vault beneath are the coffins of Pedro the Cruel and Maria Padilla his mistress, the only living being who was humanly treated by this scourge of Spain. Their three sons rest close to them. On the north and south sides of this remarkable chapel, within arched recesses, are the sarcophagi of Beatrice of Swabia and Alfonso the Learned. They are covered with cloth of gold emblazoned with coats-of-arms. A crown and sceptre rest on the cushion which lies on each tomb. In the dim light, high above and beyond mortal reach rest these two--it is very impressive. Each of the remaining twenty-nine chapels contains something of interest. In the Capilla de Santiago is a beautiful painted window of the conversion of St. Paul. The _retablo_ in the Capilla de San Pedro contains pictures by Zurbaran. In the north transept in a small chapel is a good Virgin and Child by Alonso Cano; in the south is the Altar de la Gamba, over which hangs the celebrated _La Generacion_ of Louis de Vargas, known as _La Gamba_ from the well-drawn leg of Adam. On the other side of this transept is the Altar de la Santa Cruz and between these two altars is the monument to Christopher Columbus. Erected in Havana it was brought to Spain after the late war and put up here. Murillo's work outshines all other's in the Cathedral. The grand _San Antonio de Padua_, in the second chapel west of the north aisle, is difficult to see. The window which lights it is covered by a curtain, which, however, the silver key will pull aside. Over the Altar of Nuestra Señora del Consuelo is a beautiful Guardian Angel from the same brush. Close by is another, _Santa Dorotea_, a very choice little picture. In the Sacristy are two more, _S.S. Isidore_ and _Leander_. In the Sala Capitular a _Conception_ and a _Mater Dolorosa_ in the small sacristy attached to the Capilla Real complete the list.
