Note 102 — ITER ROMANUM. V. (continued 2)
Reading edition
Magus rather signifies originally a field, or plain, and where probably the old Britons had their religious ceremonies, sports, and races, &c. the barrows too hereabout indicate here has been an ancient British temple, and I suppose the name of Long Meg and her daughters, at the British temple in Cumberland, only the remains of the original name Magus.
