Note 299 — HISTORY OF THE BRITONS.
Reading edition
An ancient scholiast adds, "He then built Guasmoric, near Lugubalia [Carlisle], a city which in English is called Palmecaster." Some difference of opinion exists among antiquaries respecting the site of Vortigern's castle or city. Usher places it at Gwent, Monmouthshire, which name, he says, was taken from Caer-Went, near Chepstow. This appears to agree with Geoffrey's account, in page 208 of this volume. See Usher's Britan. Eccles. cap. v. p. 23. According to others, supposed to be the city from the ruins of which arose the castle of Gurthrenion, in Radnorshire, Camden's Britannia, p. 479. Whitaker, however, says that Cair Guorthegirn was the Maridunum of the Romans, and the present Caermarthen. (Hist. of Manchester, book ii. c. 1.) See also Nennius, sec. 47.
