This is a painting depicting Grainne from the Irish ancient tale of Diarmaid and Grainne,
It was painted in oil and the painting was almost life size.
In Irish mythology, Gráinne (pronounced GRAWNyeah) was the daughter of Cormac mac Airt.
She was promised in marriage to Fionn mac Cumhail, but fell in love
with Diarmuid of the love spot when she saw Diarmuid in the wedding
party. She laid a geas upon him to run away with her. Their long flight
from Fionn was aided by Aengus Og, Diarmuid's foster-father.
Eventually, Fionn pardons Diarmuid after Aengus Og intercedes on their
behalf; the pair settle in Kerry and produce five children. The story
of Gráinne and Diarmuid is one of a number of instances in Irish
mythology of the eternal triangle of young man, young girl and ageing
suitor. The situation is very similar to the tale of Naoise, Deirdre
and Conchobar.
