Many stories exist about St Patricks time in Ireland. From these, two common emblems emerge. The Shamrock (seamróg in Irish), and the Snakes.
The Shamrock is a native Irish plant, from the clover family, and has a distinctive trefoil shape. St Patrick uses the three leaves of the Shamrock to explain the doctrine of Holy Trinity to the people. Just as one leaf has three distinct parts, God is really three-in-one: The Father, The Son and The Holy Spirit. Today, the shamrock plant is considered lucky. Do not confuse it with the four-leafed clover – that’s something different entirely!
