As to Geoffrey's other story, which put a brazen man on a brazen horse over Ludgate, it would appear to be a variation on the story of the brazen horse of Vergilius, but I think we may find the origin of its localisation at Ludgate in the well-known coin of Claudius, which shows an equestrian image above an arch of triumph lettered DE BRITANN. This coin is one of those occasionally found in England, and we may suppose ancient antiquaries reasoned thus about it: "It must represent a city gate in Britain; the most important is the gate of London--Ludgate." Why was the brazen horse put there? "For a terror to the Saxons" (so in Geoffrey). Who put it there? "King Lud himself, or Cadwaladr, the last British king." When did it disappear? "When the Saxons entered the city"--as in the Prophecy of Merlin, "The brazen man upon a brazen horse shall for long guard the gates of London.... After that shall the German Worm (dragon) be crowned and the Brazen Prince be buried." It was supposed to have been the palladium of Caer Lud, "and the sygte ther of the Saxons aferde."[19] For me the old British Solar God lights up the squalor of Billingsgate. The Sea God, Lud, and the brazen horse give me more pleasure than the railway bridge at Ludgate. Cæsar's sword at Bishopsgate and the head of Bran buried on Tower Hill are real city assets. London is rich in romantic lore. In her cathedral Arthur was crowned and drew the sword from the stone. Here Iseult attended the council called by King Mark. From the quay Ursula and her virgins embarked; Launcelot swam his horse over the river at Westminster, and from it Guinevere went a-maying. Possibly some day we may be as wise as Henry the Third, and put up statues to Lud and his sons at the gate which bears his name for a memorial of these things. The British legend of the foundation of London has left one tangible legacy to us even to this day in the Guildhall giants, Gog and Magog, who represent the Gogmagog of Geoffrey, a giant of the primitive people overcome by the Britons--the Magog of the Bible, who stands for the Scythian race. Thus the Guildhall Magog really represents the Ivernian race in Britain. So much for the legend. My final opinion is that the story of Caer Lud arose in an attempt to bring together the names of London, Ludgate, and Lludd, a Welsh god, and this may have been Geoffrey's work. I cannot find that the form Caer Lud was used in Welsh documents of an earlier date, although in a recent history of Wales London is so called throughout. If a single instance of "Caer Lud" could be adduced it would be different, but till that is done all derivations from Ludd must go by the board. The association of Belinus with London may in a similar way have been brought about by false etymology.[20]
