It is worth while to call to mind the kind of service for which the church was built, with its aisles and chapels and screen. The usual Sunday procession started from the north door of the presbytery, preceded by two thurifers with censers, went round behind the presbytery, the priest in his cope asperging the altars on his way, then down the south choir aisle, and through the south transept into the cloister. In the cloister-cemetery, the priest, with his ministers, said the prayers for the dead, and then rejoined the procession in the cloister Lady Chapel, where the first station was made. Thence the procession returned to the great rood in the nave, and there made the second station, the bidding-prayer being given out to the people from the rood-screen, after which it re-entered the choir. But on special occasions the ritual was increased; as, for instance, at the procession of palms on Palm Sunday, or the Corpus Christi Day procession, which is thus described by Mr J.D. Chambers[3]: "The procession, some time before the mass, should assemble in order at the step of the Choir (_i.e._ in the Presbytery), a priest in Albe and silk Cope carrying the Corpus Christi in a tabernacle or feretory under a canopy of silk raised over him and it on four staves, borne by four clerks in Albes and Tunicles, with lighted tapers. It should go out of the Choir down the Nave, and out at the West Door of the Church, round the Church and Cloisters as on Ascension Day"--_i.e._ round the outside of the whole church, beginning with the north side and returning round the east end, and through the cloister to the west door again, and thus back into the nave. The colours of the vestments at Wells followed in the main the custom of the neighbouring diocese of Sarum, but with some local variations, such as are set down in the _Consuetudinary_ which Archbishop Laud had copied from the late thirteenth-century MS. Indigo and white were used on St. John's Day and on the Dedication Festival; in Advent, indigo; at Passiontide, red, and on Palm Sunday, "except one cope of black for the part of Caiaphas" at the singing of the Passion; red, too, on Maunday Thursday, but with a banner of white. Red was also used for Easter, Pentecost, and throughout the Sundays after Trinity; while for Virgin Martyrs, red was mixed with white. This mixture of colours was probably effected by the cantors wearing different coloured copes; thus for confessors saffron _(croceus)_ was mixed with green, _sicut honestius et magis proprie possunt adaptari festo_; but St. Julian and some others had all saffron, while a few, like St. Benedict, had all indigo. White is comparatively little in evidence, but it was used at Christmas, and for commemorations of the Blessed Virgin. Black was used for the commemoration of the dead.
