refers back to the same origins, and the same were adduced in a dispute with the Abbot of Bury as to market privileges which the Londoners claimed dated from the foundation of the city before Rome was founded.[14] Perhaps there is no absolutely certain proof that the Troy story was told in London before Geoffrey’s time, but it seems likely, judging from the number of detailed London allusions in Geoffrey’s work, that there was a British and Arthurian tradition current there before he wrote. Of the latter, at least, one positive scrap of confirmation may be offered. Amongst the names appended to a deed at St. Paul’s dated 1103 is that of Arturus, a canon. This carries back the use of the name Arthur to the time of the Conquest, and we may be certain that where the name was in use, there the story of the “noble King of the Britons” was told.[15] There was a strong contingent of the Celts of Brittany in the Conqueror’s army, and to them the invasion must have seemed a re-conquest of Britain, and stories of the time before the Saxons took the “crown of London” must have been revived and spread abroad.

There is some slight possibility that when Geoffrey tells us that Belinus made a wonderful structure at the quay called after him Billingsgate, he was not merely playing on the name of “some Saxon Billings,” as has been said, for Belinus is recognised as the best known of the Celtic gods, and the name has been found in many inscriptions.[16] Geoffrey again tells us that Belinus constructed the great Roman roads in Britain, and we cannot be asked to suppose that the Roman roads were said to be the work of Belinus because the same Saxon Mr. Billings kept a posting-house.[17] The weight of evidence seems to allow of the view that there really were some remarkable Roman structures at the Tower and Billingsgate which tradition pointed to as the work of the Celtic culture-god Belinus, or of a king who bore his name. Some remnants of a building seem to have had the myth attached to them in the Middle Ages. Harrison, giving a version of the story, says of the Tower, “In times past I find this Belliny held his abode there, and thereunto extended the site of his palace in such wise that it extended over the Broken Wharf and came farther into the city, in so much that it approached near to Billingsgate, and as it is thought, some of the ruins of his house are yet extant, howbeit patched up and made warehouses, in that tract of ground in our times” (Holinshed). Belinus seems at times to have been confused with Cæsar, and so we get the Cæsar’s Tower of Shakespeare and other writers. Stow, writing of the same “ruins,” says, “The common people affirm Julius Cæsar to be the builder thereof, as also of the Tower itself.”

Nennius uses the name Belinus for Cassibelaunus, which latter, indeed, is evidently derived from the former; for he speaks of Belinus (Cassibelaunus) fighting against Cæsar. A parallel passage in Geoffrey gives Belinus the command of the army of Cassibelaunus, but in the account of the battle which follows we have no word of Belinus, but “Nennius,” a brother of Cassibelaunus and Lud, takes his place and perishes from a blow of Cæsar’s sword, Crocea Mors. “Nennius” was then buried at the North Gate of “Trinovantum” with the sword that had slain him.[18] All this is too confused to work out in detail, but it almost looks like a repeated echo of some legend which made Cassibelaunus fall in a personal encounter with Cæsar. At bottom perhaps it may have been some inscription, or coin, lettered Cuno-belin, which associated the name of Belinus with a gate of London. Such coins have been found in London. We can only be certain that at the beginning of the twelfth century the existing name of the gate was explained by a Celtic word.
