Note about the tune name "Baltiorum": From the O’Neill book “Irish Folk Music”, 1910, pgs. 198-199:
“A very ancient Irish melody is ‘Baltiorum’, and oddly enough it is known only by versions of that name. While euphonious, it conveys no meaning to the reader, and it is commonly assumed that notwithstanding its Latin termination it signifies something in the Irish language. And so it does when understood. The first writer who undertakes to explain it is Edward Bunting. ‘Baal tigh abhoran’, usually called ‘Baltiorum,’ is a tune which might perhaps be assigned to the Pagan period, in as much as it is still customarily sung at the bonfires lighted on St. John’s Eve, the anniversary of Baal-tinne, and has so been sung from time immemorial. He does not give the translation in English, although his dissertation is much more comprehensive than the extract above quoted. To the writer it appears to be the song of praise or worship of Baal, the Fire-God.
The Pagan festivals eventually were wisely turned into account as Christian holidays, and in this instance the Baal-tinne, or fire lighted to welcome the Samhain or summer solstice, was continued as the celebration of St. John’s eve. The melody, Conran tells us in his ‘National Music of Ireland’ (1850), may still be heard from the groups assembled around these bonfires. In the writer’s boyhood days the melody was forgotten and so was the Pagan significance of the celebration.”
