added in 1255; apparently this was originally of wood, but that stone vaulting was intended may be inferred from the flying buttresses in some of the pictures of the Cathedral. The view along the nave, as represented in Hollar's engraving is very fine, and reminds one of the noble nave at Ely. Both the nave and choir had twelve bays counting from the west door. The second bay of the north side contained the Court of Convocation, and close by was the font near which Sir John Montacute desired in his will (1388) to be buried. 'If I die in London, then I desire that my body may be buried in St. Paul's, near to the font wherein I was baptized.' In the tenth bay was the Chantry Chapel of Thomas Kempe, bishop of the diocese (1448-1489), and rebuilder of Paul's Cross. In the eleventh bay, on the south side, was the tomb of Sir John Beauchamp, K.G. (d. 1358), Constable of Dover Castle, and son to Guy Beauchamp, Earl of Warwick. This tomb was commonly called after Duke Humphrey, and the nave of the church from this misnomer went by the name of Duke Humphrey's Walk. On May Day watermen and tankard-bearers came to the tomb early in the morning, strewed herbs upon it and sprinkled it with water. At the foot of this tomb was the image of the Virgin, before which a lamp was kept perpetually burning, and every morning after matins a short office was said before it. A taper was also kept burning before the Great Crucifix, near to the north door, fabulously said to have been discovered by King Lucius, A.D. 140. Richard Martin, Bishop of St. David's in the reign of Edward IV., had a special veneration for this crucifix, and left an annual gift to the choristers that they might sing before it _Sancte Deus fortis_.[365] In the north aisle was the famous _Si quis_ door, on which notices were fixed; originally these were probably purely ecclesiastical, but in course of time all classes made their wants known there. Decker writes: 'The first time that you venture into Paul's, pass through the body of the church like a porter, yet presume not to fetch so much as one whole turn in the middle aisle, no, nor to cast an eye to _Si quis_ door, pasted and plastered up with serving-men's supplications, before you have paid tribute to the top of Paul's steeple with a single penny.' Bishop Hall, in his _Satires_, shows that Churchmen could be hired there too-- 'Sawst thou ever _Si quis_ patched on Paul's church door, To seek some vacant vicarage before?' This practice is alluded to by Chaucer:-- 'He sette not his benefice to hyre, And leet his sheepe encombred in the myre, And ran to Londoun unto Saint Paules, To seken hym a chaunterie for soules.' (Prologue to _Canterbury Tales_.)
