In a letter among his MSS. in the British Museum Bishop Pococke discusses the dragon legend. He dates from "Highworth, April 12th, 1757," and the following expresses his views:—
" A mile further is the hamlet of Up Lamborn, which is a pretty place We went up the down to the right of it, and in three miles came to the camp over the White Horse, at the end of these hills. They command a glorious prospect into Wiltshire, Berkshire, Oxfordshire, and Gloucestershire. We passed a line to the east of it. The camp itself ii defended by one deep fosse. It is of an irregular form of four sides, about 800 paces in circumference. To the north-east of it is a small hill like a barrow, which was cut off from it. It is called Dragon Hill. On the side of the hill over it, just under the camp, is the White Horse, cut in turf as if in a trot. The green sod remains to form the body. It may be a hundred yards in length, and is well designed. On Dragon Hill the common people say St. George killed the dragon. They show a spot on it which they affirm is never covered with grass, and there they say the dragon was killed, and I think buried, and that the white horse was St. George's steed.
