LLANVIHANGEL-AR-ARTH, or YEROTH (LLAN-FIHANGEL-ARARTH), a parish, in the union of NEWCASTLE-EMLYN, higher division of the hundred of CATHINOG, county of CARMARTHEN, SOUTH WALES, 12 miles (N. by E.) from Carmarthen; containing 1993 inhabitants. According to Giraldus Cambrensis, this place Was the scene of an obstinate battle between Hywel and Grufydd ab Llewelyn, in 1039, in which the former, who had brought his wife to the field to be a spectator of his anticipated triumph, wad defeated by the latter, and obliged to seek safety by flight; but, being pursued by the conqueror, he was taken prisoner with his wife, and detained in the power of Grufydd. Rh$s ab Grufydd, according to the same historian, held an interview at the same place with Henry II., in 1102, when he made his formal submission to the authority of that monarch. The parish is pleasantly situated on the river Teivy, over which the turnpike-road between Carmarthen and Aberystwith is continued by means of a handsome stone bridge; and extends for nearly eight miles in length from north to south, and seven miles in breadth from east to west. The surrounding scenery is pleasingly diversified, and in some parts highly picturesque; and the soil, though varying in different parts, is in general fertile. Fairs are annually held, on the 12th of May and the 10th of October, in the village, which, in addition to its public situation on the thoroughfare leading from Carmarthen to Aberystwith, is also intersected by the turnpike-road from the former town to Lam-peter. The living is a discharged vicarage; rated in the Icing's books at £6. 6. 8., endowed with £200 royal bounty, and in the alternate patronage of W. Lewes, and J. E. Lloyd, Esqrs., the =proprietors: the tithes have been commuted for a rent- charge of £508, of which £430 are payable to the impropriators, and £78 to the vicar, who has also a glebe of 85 acres, valued at £60 per annum. The church, dedicated to St. Michael, is situated on an eminence on the southern bank of the Teivy, commanding an eaten, sive and pleasing view of the river and the adjacent country; and hi the churchyard is a Raman monumental stone, with the inscription Hie Jam Madam Filters SenomaciE.
