Vergobretus, the magistrate of the Ædui, is explained either as Fear-co-breith, man who judges, or War-cy-fraith, man placed over the laws; or, taking gwr as excelling, and brawd, as justice, he would be excelling in justice.
Viriathus must be referred to fear, man, and, perhaps, to aodh, fire.
Vercingetorix himself may be translated into Fear-cuin-cedo-righ, man who is chief of a hundred heads; and his cousin, Vergosillanus, is the man either of the banner or the spear, according as sillanus is referred to saighean, a banner, or to saelan, a spear.
Here, then, are the tokens of kindred between the Gauls of the continent and the Gael of our islands, for Fear, the frequent commencement in both Ireland and Scotland, is assuredly the word that Cæsar rendered by Vir, more correctly both in sense and sound than he knew.
Fearghus, man-deed, from gus, a deed, is the rendering of one of the most national of Gaelic names, though Macpherson makes it Fearguth, man of the word.
Bold genealogists place Feargus at the head of the line of Scottish kings, and make him contemporary with Alexander the Great. Another Fergus was son of Finn, and considered as even a greater bard than his nephew, Oisean. Poems said to be by him are still extant, in one of which he describes his rescue of his brother, Oisean, who had been beguiled into a fairy cave, and there imprisoned, till he discovered himself to his brother by cutting splinters from his spear, and letting them float down the stream that flowed out of the place of his captivity.
Fearghus, the son of Erc, a Dalriad prince, was, in 493, blessed by St. Patrick, and led the great migration of Scots to Albin, together with his brothers Loarn and Aonnghus, who each named their own district, while he reigned over the whole region of the Scots,—that around Argyle; whither he had transported the stone of dominion, that sooner or later brought conquest to the race who possessed it. From these Fearghus or Farghy in Ireland, Fergus in Scotland, and the feminine Fergusiana still continue in use.
Fearachar is another Scottish form. Ferquard is given as prince of the Scots in Ireland, at some incalculable time; and Fearchur or Ferchar was the king of the Scots just after St. Columbus' death. He is Latinized as Ferquardus; and this was the name of an Earl of Ross in 1231; and as Farquhar has continued in favour in the Highlands. Feardorcha is the blind man. Fardorougha is an incorrect modernism, and Ferdinand and Frederick the supposed equivalent.
Gwr, or Wr, is the Cymric form of the same word, and the parallel to Fergus among the Picts was Wrguist, or Urguist, a prince who lived about 800, and whose daughter was called after him, married the Scottish Eacha or Fergusiana, and thus led to the union of the two races under her descendant, Kenneth MacAlpin.
Gwrtigearn, excelling king, is a Silurian prince of doubtful fame. Through Latinism we know him as Vortigern. It would seem that when the usurpation of Maximus had involved the Roman empire in confusion, and left Britain without any legions to defend it against the robber nations round, that he made some attempt at a partial revival of national spirit; but, failing this, entered into a treaty with the Anglo-Saxon invaders, and was thought to have betrayed the cause of his country.
