JOHN THE BAPTIST
The shell with three water drops is a symbol of baptism generally, and particularly of the baptism of Christ. The three droplets remind us of the Trinity — Father, Son and Holy Spirit — into which Christians are baptized. The shell alone may also be used as a symbol for pilgrimage, and is often used as an emblem for saints known for their travels or whose shrines have become destinations for pilgrims.
