Under the patronage of the Pope, Michelangelo experienced constant interruptions to his work on the tomb in order to accomplish numerous other tasks. Although Michelangelo worked on the tomb for 40 years, it was never finished to his satisfaction.[34] It is located in the Church of S. Pietro in Vincoli in Rome and is most famous for the central figure of Moses, completed in 1516.[35] Of the other statues intended for the tomb, two known as the Rebellious Slave and the Dying Slave, are now in the Louvre.[34]
