St. Catherine of Alexandria was a 4th-century Christian martyr and saint. According to tradition, she was a learned and beautiful woman who converted to Christianity and became a noted defender of the faith. She was imprisoned and subjected to various tortures, including being broken on a wheel, but survived. She is said to have converted the emperor Maxentius to Christianity before her ultimate execution. St. Catherine is the patron saint of philosophers, students, and preachers and is venerated by the Roman Catholic, Orthodox, and Coptic Churches.

According to tradition, St. Andrew was crucified on an X-shaped cross, known as a Saint Andrew's Cross. This distinctive form of crucifixion is said to have been chosen as a reflection of St. Andrew's humility, as he felt unworthy to be crucified in the same manner as Jesus Christ. The image of St. Andrew holding the X-shaped cross has been a popular subject in Christian art and is a symbol of the saint's martyrdom. St. Andrew is the patron saint of Scotland and is revered by the Roman Catholic, Orthodox, and Anglican Churches.

St. Lawrence of Rome was a Christian martyr and deacon who lived in the 3rd century. He is venerated as a saint by the Roman Catholic, Eastern Orthodox, and Anglican Churches. According to tradition, Lawrence was appointed by Pope Sixtus II as one of the seven deacons of Rome, responsible for distributing alms to the poor. When the Roman emperor Valerian began a persecution of the Christians, Pope Sixtus was executed, and Lawrence was ordered to turn over the Church's treasure. Instead, Lawrence gathered the poor and the infirm and presented them to the authorities, saying, "Here is the Church's treasure." He was then subjected to a brutal martyrdom, during which he was roasted alive on a gridiron. Despite his suffering, Lawrence is said to have remained joyful and even to have joked with his executioners. He is remembered for his faith and for his courage in the face of persecution, and his feast day is celebrated on August 10th.
