Pepys, speaking of the visit to the cathedral of himself and some friends in 1661, tells, in his diary, that they went "then away thence, observing the great doors of the church, as they say, covered with the skins of Danes." He is so accurate an observer that this must be taken as conclusive evidence that there was such a tradition in his time, and some ground for it, though no other record of anything of the kind is to be found. However, even if it were likely, which many people will deny, that the skins of Danes were ever nailed to church doors at Rochester, it certainly is not that they would have been transferred by Normans from the Saxon cathedral to their new one, or that, if so transferred, they would have survived the fires and other dangers through which this afterwards passed. There are traditions of the existence of human skin on doors at Worcester Cathedral, where it is said to have belonged to a robber who stole the sanctus bell from the high altar, and at Hadstock and Copford, East Anglian churches. In these latter cases the Danes are again mentioned. In 1848 all these doors had been removed from their original positions (the old north doors of Worcester being still preserved in the crypt) but Mr. Way succeeded in obtaining fragments of the parchment-like substance from each for microscopic examination. They were declared to be, in each case, human in their origin, and to have belonged probably to fair-haired persons. These cases show flaying not to have been unknown in England, even, to judge by the Worcester case, after the Norman Conquest, and confirm the passages in records that seem to refer to its existence. #The Nave# has nothing else remarkable in its exterior. The perpendicular windows in the north aisle wall, part of which was rebuilt in 1670, are two-lighted, with irregular quatrefoils in their heads. Those of the southern aisle, which was re-cased in 1664, are single-light, and only three in number,--in the second, third, and fourth bays from the west. The insertion of Perpendicular windows in the aisles took place about the middle of the fifteenth century. The plainness of the south side, where the Lady Chapel does not hide it, is perhaps explained by the fact that it used to be hidden by the Cathedral Almonry. The westernmost bay of each aisle is plain, and the next on the north side contains the now walled-up Perpendicular doorway, inserted, when their new church was built, for the entry, in their solemn processions, of the parishioners of St. Nicholas, who passed out again by the west door. It is contained within a rectangular framework, and has quatrefoils in the spandrels.
