For the children of Dôn were certainly gods of the sky. Their names are writ large in heaven. The glittering W which we call “Cassiopeia’s Chair” was to our British ancestors _Llys Dôn_, or “Dôn’s Court”; our “Northern Crown” was _Caer Arianrod_, the “Castle of Arianrod”, Dôn’s daughter; while the “Milky Way” was the “Castle of Gwydion”, Dôn’s son.[282] More than this, the greatest of her children, the Nudd or Lludd whom some make the head of a dynasty of his own, was the Zeus alike of the Britons and of the Gaels. His epithet of _Llaw Ereint_, that is, “of the Hand of Silver”, proves him the same personage as Nuada the “Silver-Handed”. The legend which must have existed to explain this peculiarity has been lost on British ground, but it was doubtless the same as that told of the Irish god. With it, and, no doubt, much else, has disappeared any direct account of battles fought by him as sky-god against Fomor-like enemies. But, under the faint disguise of a king of Britain, an ancient Welsh tale[283] records how he put an end to three supernatural “plagues” which oppressed his country. In addition to this, we find him under his name of Nudd described in a Welsh Triad as one of “the three generous heroes of the Isle of Britain”, while another makes him the owner of twenty-one thousand milch cows—an expression which must, to the primitive mind, have implied inexhaustible wealth. Both help us to the conception of a god of heaven and battle, triumphant, and therefore rich and liberal.[284] More tangible evidence is, however, not lacking to prove the wide-spread nature of his worship. A temple dedicated to him in Roman times under the name of Nodens, or Nudens, has been discovered at Lydney, on the banks of the Severn. The god is pictured on a plaque of bronze as a youthful deity, haloed like the sun, and driving a four-horsed chariot. Flying spirits, typifying the winds, accompany him; while his power over the sea is symbolized by attendant Tritons.[285] This was in the west of Britain, while, in the east, there is good reason to believe that he had a shrine overlooking the Thames. Tradition declares that St. Paul’s Cathedral occupies the site of an ancient pagan temple; while the spot on which it stands was called, we know from Geoffrey of Monmouth, “Parth Lludd” by the Britons, and “Ludes Geat” by the Saxons.[286]
