Michelangelo stated, “Many believe —and I believe—that I have been designated for this work by God. In spite of my old age, I do not want to give it up; I work out of love for God and I put all my hope in Him.”
When he was 74 years old, Michelangelo received a contract from the Catholic Church to finish building St. Peter's Basilica. Before passing away at age 88, he continued to work in the church for an additional 14 years. As it became physically hard for him to visit the job site frequently during this period, he was forced to supervise the project from home by submitting drawings and blueprints and responding to trustworthy foremen's work.
