"Our Lady, Star of the Sea is an ancient title for the Virgin Mary, mother of Jesus Christ. The title was used to emphasize Mary's role as a sign of hope and as a guiding star for Christians, especially gentiles, whom the Old Testament Israelites metaphorically referred to as the sea. Under this title, the Virgin Mary is believed to intercede as a guide and protector of those who travel or seek their livelihoods on the sea."
Inspired by the song by Moby, Stella Maris:[link]
and medieval mysticism.
