St. Catherine is shown with a Crown of Thorns, symbolizing her suffering for Jesus, also adoring the crucifix wrapped in the Dominican habit.

Catherine of Siena (1347-1379) is a Doctor of the Church affiliated with the Domicians, founded by St. Dominic over a hundred years before her time in 1217. She would have been familiar with St. Thomas of Aquinas writings (1225-1274) also a Doctor of the Church and a Domincan. Both St. Catherine of Siena, St. Thomas Aquinas and St. Albert the Great, all Domincans, are considered the Middles Age Church Doctors, along with St. Anthony of Padua and St. Bonaventure. The Dominicans have been instrumental in spreading the rosary and emphasizing the power given by reciting and meditating on the rosary.
