Mona
(
Μόνα). The modern Anglesey (Angles Ey,
“Englishman's island”); an island off the coast of the Ordovices in
Britain, one of the chief seats of the Druids. Caesar erroneously describes this island as
half way between Britannia and Hibernia (
B. G. v. 13). Hence it has been
supposed by some critics that the Mona of Caesar is the Isle of Man; but it is more probable,
on account of the celebrity of Mona in connection with the Druids, that he had heard of
Anglesey, and that he received a false report respecting its real position. The island was
taken in A.D. 61 by Suetonius Paulinus, who broke the power of the Druids; and was again
subdued by Agricola in A.D. 78 (
Agric. 18;
Ann. xiv. 29). See
Monapia.
