The story of St. George treading on the Padstow Rock, and the subsequent gush of water, is immediately suggestive of the Pegasus legend. Pegasus, the winged steed of the Muses, which, with a stroke of its hoof, caused a fountain to gush forth, is supposed to have been thus named because he made his first appearance near the _sources_--Greek _pegai_--of Oceanus. It is obvious, however, from the coins of Britain, Spain, and Gaul, that Pegasus--occasionally astral-winged and hawk-headed--was very much at home in these regions, and it is not improbable that _pegasus_ was originally the Celtic _Peg Esus_. The god Esus of Western Europe--one of whose portraits is here given--was not only King Death, but he is identified by De Jubainville with Cuchulainn, the Achilles or Young Sun God of Ireland.[293] Esus, the counterpart of Isis, was probably the divinity worshipped at Uzes in Gaul, a coin of which town, representing a seven-rayed sprig springing from a brute, is here reproduced, and that King Esus or King Osis was the Lord of profound speculation, is somewhat implied by _gnosis_, the Greek word for knowledge. Tacitus mentions that the neighing of the sacred white horse of the Druids was regarded as oracular; the voice of a horse is termed its neigh, from which it would seem horses were regarded as super-intelligent animals which _knew_.[294] The inscription CUN or CUNO which occurs so frequently on the horse coins of Western Europe is seemingly akin to _ken_, the root of _know_, _knew_, _canny_, and _cunning_. In India the elephant _Ganesa_--seemingly a feminine form of _Genesis_ and _Gnosis_--was deemed to be the Lord of all knowledge. In connection with Pegasus may be noted Buk_ephalus_, the famed steed of Alexander. The Inscriptions EPPILLUS and EPPI[295] occur on the Kentish coins, Figs. 122 and 123; _hipha_ or _hippa_ was the Phoenician for a mare; in Scotland the nightmare is known as _ephi_altus; a _hippo_drome is a horse course, whence, perhaps, Bukephalus may be translated Big Eppilus. The little elf or elve under a bent sprig is presumably Bog or Puck, and in connection with the _Eagle_-headed Pegasus of Fig. 164 may be noted the Puckstone by the megalithic _Aggle_ Stone at Pur_beck_, where is a St. Alban's Head.[296] [Illustration: FIGS. 122 and 123.--British.
