Until 1533 Michael Angelo worked at the Medici monuments.

The ever recurring trouble about the Tomb of Julius distracted him in 1532; a new contract was made out in the May of that year, and Michael Angelo evidently expected that he would have to go to Rome about it.

This may be gathered from the important letter written on February 24, 1531, by Sebastiano del Piombo, in Rome, to Michael Angelo, in Florence; it marks the renewal of the intercourse of the two old friends after the dangers and troubles they had passed through during the siege of Florence and the sack of Rome.
Sebastiano's previous letter, as far as we know, is dated April 25, 1525:-- _1531, 24th February._ "MY DEAREST COMRADE,--By Master Domenico, called Menichella, who has been to see me on your behalf.

God knows how dear it was to me.

After so many sorrows, hardships, and dangers, Almighty God has left us alive and well in His mercy and pity.
