When St Catherine of Siena died in Rome, her hometown of Siena, Italy, wanted her body. Realizing they would probably get caught if they took her whole corpse, the Siena thieves decided that it would be safer if they just took her head.
When they were stopped on their way out by guards outside of Rome, they said a quick prayer, asking for St. Catherine of Siena’s intercession. The guards opened the bag and did not find the dead head of St. Catherine, but a bag full of rose petals. Once the thieves were back in Siena, Catherine’s head re-materialized, one of the many miracles attributed to the saint.
The head of St. Catherine of Siena was placed in a reliquary in the Basilica of St. Dominic in Siena, where it can still be venerated today, along with her thumb. Her body remains in Rome, her foot is venerated in Venice.
I’ve been to the Basilica of St Dominic and felt a sense of peace looking at the metal box containing her head and praying for her intercession.
