The church of Santi Cosma e Damiano sits right on the edge of the Roman Forum and is dedicated to two physician saints who were martyred under Diocletian in the year 287, when they were beheaded for their faith. They became tremendously well known, and, because of their work as doctors (medici), the Medici family in Florence embraced them. Perhaps the most curious aspect of the church is the location in the Roman forum.

On this day we return to San Lorenzo (Saint Lawrence), one of seven pilgrimage churches of Rome, which were churches established for incoming pilgrims as "the" seven churches to visit on a pilgrimage. St. Laurence was a deacon of the church, an ally and associate to the pope, and was immensely popular in Rome. We have already visited the place of his martyrdom in the Church of San Lorenzo in Panisperna where the grill on which he was martyred is contained.

The Basilica Santi Apostoli, located centrally in Rome near Piazza Venezia, holds the relics of St. Philip and St. James the Lesser, rediscovered in the late 1800s. Originally built in the mid-300s, the current structure is a result of multiple rebuilds, including an 1800s renovation. It was also Michelangelo's initial burial site before his body was moved to Florence.
