Ortírielyanna is a translation of the Sub tuum praesidium into Quenya made by J.R.R. Tolkien in the 1950s. It was published in Vinyar Tengwar, Number 44, June 2002 in 2002, edited by Patrick H. Wynne, Arden R. Smith, and Carl F. Hostetter.
The Sub tuum praesidium is the oldest known hymn to Virgin Mary and is often used in Christian services as a prelude to the Litany of the Blessed Virgin Mary (also known as the Litany of Loreto). In 1944, Tolkien recommended his son Christopher to learn "the Litany of Loretto (with the prayer Sub tuum praesidium)" by heart. It was therefore logical that Tolkien created his own Quenya Litany of Loreto, which immediately follows in the same manuscript as the Ortírielyanna.
