Of the chapels and altars once existing we have records in various documents. In the "Sarum Processional" twelve altars are mentioned, dedicated respectively to SS. Andrew, Nicholas, John the Baptist, Margaret, Mary Magdalene, Laurence, Michael, Martin, Catherine, Edward, Edmund the King, and Edmund, Archbishop of Canterbury. The sites of these so far as they can be traced appears to have been: St. Catherine and St. Martin in the north choir transept, St. Nicholas and St. Mary Magdalene in the south, and St. Edmund of Canterbury and St. Margaret respectively in the north and south great transepts. Throughout the nave it is evident that the first plans were rigidly obeyed, although the severity of the early years of the style had become much modified before the work was finished. The absence of ornate decoration, the simplicity of the mouldings, and the plate-tracery of the triforium all indicate the first period of "Early English." [Illustration: NAVE TRANSEPT.] The dimensions of the nave are: 229 feet 6 inches long, 82 feet wide, and 81 feet high. The aisles are 17 feet 6 inches wide, and 39 feet 9 inches high. =The Nave Transepts= are in three stories, with eastern aisles divided into three bays. The screens inclosing chapels in these were demolished by Wyatt. Above the entrances to the great transepts are arches inserted by Bishop Beauchamp (1450-1481) to withstand the side thrust of the great tower. These are of perpendicular work, with their spandrils panelled and their cornices battlemented, as shown in the engraving. Canterbury and Wells, in a far more prominent fashion, have similar features; in this instance the addition appears to have succeeded in its purpose to insure the stability of the tower. In the choir transepts these additional features take the form of an inverted arch, above the main arch. The vaulting of the tower roof is also in the perpendicular style and shows excellent groined work. Both Sir Christopher Wren and Francis Price, call its four main pillars the legs of the tower. Of the transept Fuller says: "The cross aisle of this church is the most beautiful and lightsome of any I have yet beheld. The spire steeple (not founded on the ground, but for the main supported by four pillars,) is of great height and greater workmanship. I have been credibly informed that some foreign artists beholding this building brake forth into tears, which some imputed to their admiration (though I see not how wondering could cause weeping): others to their envy, grieving that they had not the like in their own land."
