[28] I take some credit to myself for this conjecture as to the original meaning of “the other half stone.” And I have, long since writing this, accidentally discovered what strongly confirms my opinion. The authors of the Beauties of England and Wales, speaking of inscribed stones at Ebchester, in Durham, say, there is one having the single word “Have” for Ave on it. This stone is supposed by Horsley to be sepulchral. Have Melitina Sanctissima. The custom of thus saluting, as it were, the dead, or taking their last farewell of them, is very well known, and it may seem almost needless to produce any instances of it. Thus Æneas bids eternal adieu to Pallas: Salve æternum mihi, maxime Palla, Æternumque vale.――Æneid, XI. 97. Thus also a passage in Catullus,――Ave atque vale. [29] DRUID, DRUIDES, OR DRUIDæ.――Some derive this word from the Hebrew Derussim, or Drussim; which they translate Contemplatores. Pliny, Salmasius, Vignierius, and others, derive the name from δρυς, an oak, on account of their inhabiting, or at least frequenting and teaching in forests, or because they sacrificed under the oak. Menage derives the word from the old British “Drus,” which signifies “Dæmon” or “Magician;” Borel, from the old British “Dru” or “Deru;” whence he takes δρυς to be derived. Goropius Becanus, lib. i. takes “Druis” to be an old Celtic or German word, formed from “trowis” or “truis,” signifying a “Doctor of the Truth and Faith.” Father Peyron, in his book of the Original of the Celtic Language, will have both Greek and Latin to come from Celtic; and if so, the Greek word δρυς must come from the Celtic “deru.” The groves where they worshipped were called Llwyn; thence, probably, is derived the word “Llan,” signifying now, in Welch, a church. These groves were inclosures of spreading oak, ever surrounding their sacred places; and in these words, “1st. Gorseddan,” or Hillocks, where they sat, and from whence they pronounced their decrees, and delivered their orations to the people; “2nd. Carnedde,” or Heaps of Stones, on which they had a peculiar mode of worship; “3rd. Cromlech,” or Altars, on which they performed the solemnities of sacrifice. There were several orders of them:――1st. Druids; the chief of these was a sort of Pontifex Maximus, or High Priest; these had the care and direction of matters respecting religion; 2nd. Bards; who were an inferior order to the Druids, and whose business it was to celebrate the praises of their heroes, in songs composed and sung to their harps; 3rd. Eubates; who applied themselves chiefly to the study of Philosophy, and the contemplation of the wonderful works of Nature.
