or Holy Island. Ireland was so called because of its many saints, and Guernsey for its many monks. The island referred to by Thomas Moore in his Irish Melodies (No. II.) is Scattery, to which St. Senanus retired, and vowed that no woman should set foot thereon.
Oh, haste and leave this sacred isle, Unholy bark, ere morning smile.
St. Senanus and the Lady.
Enhallow (from the Norse Eyinhalga, Holy Isle) is the name of a small island in the Orkney group, where cells of the Irish anchorite fathers are said still to exist.
