Bedfordshire; in the Mayor’s Chapel, Bristol; in Gloucester Cathedral; in the church of Stratford-upon-Avon, Warwickshire; and in Rothwell Church, Northamptonshire: these are beneath canopies, and most of them are highly enriched. Quintuple sedilia sometimes occur, but are very rare; in the conventual church of Southwell, Nottinghamshire, are, however, five sedilia beneath ogee-headed canopies richly ornamented. A single sedile for one person only is occasionally met with, but not often. [Illustration: Double Piscina, Salisbury Cathedral.] Eastward of the sedilia, in the same wall, is a _fenestella_ or niche, sometimes plain, but often enriched with a crocketed ogee or pedimental hood moulding in front, over the arch, which is trefoiled or cinquefoiled in the head. This niche contains a hollow perforated basin or stone drain, called the _piscina_ or _lavacrum_[186-*], into which it appears that after the priest had washed his hands, which he was accustomed to do before the consecration of the elements and again after the communion, the water was poured, as also that with which the chalice was rinsed. The usage of washing the hands before the communion is one of very high antiquity, and is expressly noticed in the Clementine Liturgy, and by St. Cyril in his mystical Catechesis[187-*]; we do not, however, find the piscina in our churches of an era earlier than the twelfth century, and even then it was of uncommon occurrence; but in the thirteenth century the general introduction is observable. In Romsey Church, Hampshire, is the shaft and basin (the latter cushion-shaped) of a curious Norman piscina: this is now lying loose, in a dilapidated state. In the south apsis of the same church is another Norman piscina, consisting of a quadrangular-shaped basin projecting from the south wall; and on the south side of the chancel of Avington Church, Berkshire, is a plain Norman piscina within a simple semicircular arched recess. The churches of Kilpeck, Herefordshire, Keelby, Lincolnshire, and Bapchild, Kent, also contain Norman piscinæ. Those of all the various styles of later date are common; they exhibit, however, an interesting variety in design and ornamental detail. The drain of the piscina communicated with a perforated stone shaft, commonly enclosed in the wall, through which the water was lost in the earth; as in the case of the piscina with its shaft taken out of the south wall of the chancel of the now destroyed church of Newnham Regis, Warwickshire. Sometimes a piscina was a subsequent addition to a structure of early date, as in the old and now demolished church of Stretton-upon-Dunsmore, Warwickshire, in the south wall of the Norman chancel of which a piscina of the latter part of the thirteenth century had been inserted.
