This is "The Phantom Queen", also known to many as The Morrigan, and "The Chant to the Phantom Queen" are both hand fired premium parchments affixed to this collage. There are two pewter feathers beneath he art and below that is the celtic symbol the triquetra and a hand stamped and embossed moon in silver under the chant. Beautiful devotional piece for a priestess of the Morrigan.
The Morrigan is a goddess of battle, strife, and fertility. Her name translates as either "Great Queen" or "Phantom Queen," and both epithets are entirely appropriate for her. The Morrigan appears as both a single goddess and a trio of goddesses. The other deities who form the trio are Badb ("Crow"), and either Macha (also connotes "Crow") or Nemain ("Frenzy"). The Morrigan frequently appears in the ornithological guise of a hooded crow. She is one of the Tuatha Dé Danann ("Tribe of the goddess Danu") and she helped defeat the Firbolg at the First Battle of Mag Tuireadh and the Fomorians at the Second Battle of Mag Tuireadh.
