The cover art of Cruachan's Pagan was made by John Howe, the one behind the illustrations of the books "The Lord of the Rings". The cover is a painting called "Celtic Myth". The first track, "Michael Collins" of course refers to the Irish revolutionary leader, not the man who orbited the moon during the 1969 landing by Armstrong and Aldrin (who has also had musical tributes).
The legendary Cruachan was a Royal Palace, home of Medb (or Meave) "the drunken one", Warrior Queen and Earth Goddess. Fierce and proud, she was responsible for launching the famed cattle raid of Cooley, as recounted in one of the greatest works of early Irish literature, the Táin Bó Cúailnge.
