Among the wispy clouds stands a Celtic Cross, and in the center sits the Trinity Knot. The Trinity Knot can represent various meanings such as birth, life, death, or birth, death, and rebirth. From a Christian perspective, it represents the three persons of God, the Father, Son and Holy Spirit. Although mostly unverified, stories and traditions came about connecting St. Patrick with using the Celtic Cross to spread Christianity, and it is now a symbol of his feast day on March 17th.
