The terminal letter in the third line[140] was already defective in the time of Edward Lhwyd, as shown by the figure of it in his sketch. (See woodcut, No. 15.) Sibbald prints it as a K, a letter without any attachable meaning. Lhwyd read it as an F (followed apparently by a linear point or stop), and held it to signify--what F so often does signify in the common established formula of these old inscriptions--F(ILIVS). The upright limb of this F appears still well cut and distinct; but the stone is much hollowed out and destroyed immediately to the right, where the two cross bars of the letter should be. The site of the upper cross-bar of the letter is too much decayed and excavated to allow of any distinct recognition of it. The site, however, of a small portion of the middle cross bar is traceable at the point where it is still united to and springs from the upright limb of the letter. Beyond, or to the right of this letter F, a line about half-an-inch long, forming possibly a terminal stop or point of a linear type, commences on the level of the lower line of the letters, and runs obliquely upwards and outwards, till it is now lost above in the weathered and hollowed-out portion of stone. Its site is nearer the upright limb or basis of the F than it is represented to be in the sketch of Mr. Lhwyd, where it is figured as constituting a partly continuous extension downwards of the middle bar of the letter itself. And perhaps it is not a linear point, but more truly, as Lhwyd figures it, the lower portion of a form of the middle bar of F, of an unusual though not unknown type. The immediate descent or genealogy of those whom these Romano-British inscriptions commemorate is often given on the stones, but their status or profession is seldom mentioned. We have exceptions in the case of one or two royal personages, as in the famous inscription in Anglesey to "CATAMANUS, REX SAPIENTISSIMUS OPINATISSIMUS OMNIUM REGUM." The rank and office of priests are in several instances also commemorated with their names, as in the Kirkmadrine Stone in Galloway. In the churchyard of Llangian, in Caernarvonshire, there is a stone with an ancient inscription written not horizontally, but vertically (as is the case with regard to most of the Cornish inscribed stones), and where MELUS, the son of MARTINUS, the person commemorated, is a physician--MEDICVS. But the inscription is much more interesting in regard to our present inquiry in another point. For--as the accompanying woodcut of the Llangian inscription shows--the F in the word FILI is very much of the same type or form as the F seen by Lhwyd in the Cat-stane, and drawn by him. (See his sketch in the preceding woodcut, Fig. 15.) The context and position of this letter F in the Llangian legend leaves no doubt of its true character. The form is old; Mr. Westwood considers the age of the Llangian inscription as "not later than the fifth century."[141] An approach to the same form of F in the
