[25] When the English conquered Somerset from the Brit-Welsh, they translated the Celtic Ogo into Hole, whence the cave and village of Wookey Hole were named, just as they translated a neighbouring hill, called Pen, into Knowle, the generic Celtic term in each case being used to specify a particular object. There are many other instances of the like use of a Celtic name by the English conquerors of the Celts. In the Limestone plateau of Llanamynech, near Oswestry, there is a cave called “The Ogo.”

[27] The cave is accessible, and can be examined without any climbing.
[28] Both of these caves are kept in excellent order, and the latter is lighted with gas.
[29] The cave is admirably preserved by the care of the owner, J. Farrer, Esq., and may be visited without any difficulty.
