In the south-east corner, under Anselm's Tower, is a chapel generally known as that of St. John, sometimes as that of St. Gabriel. It has been divided into two compartments by a wall. There are some very interesting paintings[2] on the roof, representing Our Lord in the centre of the angelic host, the Adoration of the Magi, and a figure of St. John; this work is believed to be of the thirteenth century. The central pillar of this chapel, with the curved fluting in the column and the quaintly grotesque devices of the figures carved on the capital, is well worthy of close examination. The grate that we see here was erected by the French Protestants, large numbers of whom fled to England during the persecution which was instituted against their sect in 1561. They were welcomed by Queen Elizabeth, and allowed to settle in Canterbury, where the cathedral crypt was made over to them to use as a weaving factory. It is possible that the ridges in the floor of St. John's Chapel are marks left by their looms, but more evident trace of their occupation is afforded by the inscriptions in French painted on the pillars and arches of the main crypt, and again by the custom which still survives of holding a French service in the south aisle of the crypt; this part has been walled off especially as a place of worship for the descendants of the French exiles, and here service is still held in the French tongue. Alterations have been lately made by which the French service is held in the Black Prince's Chantry, and the part of the crypt formerly walled off has been merged with the rest of the crypt, which is thus completely thrown open. Access to the French church is now obtained from the crypt, and not from outside. This chantry was founded by the Black Prince in 1363 to commemorate his marriage with his cousin Joan, the "Fair Maid of Kent." Here, according to the prince's ordinance, two priests were to pray for his soul, in his lifetime and after; the situation of the two altars, at which the priests prayed, can still be traced. On the vaulting we see the arms of the prince, and of his father, and what seems to be the face of his wife. In return for the permission to institute this chantry, the prince left to the monastery of Canterbury an estate which still belongs to the Chapter, the manor of Fawkes' Hall. This was a piece of land in South Lambeth, which had been granted by King John to a baron called Fawkes. His name still survives in the word "Vauxhall."
