Born in Naples in 1598, died in Rome in 1680, working almost the entire time.
He was a prodigy of the sort that makes other artists uncomfortable — a pope reportedly predicted, after watching the boy draw a head in about an hour, that he would be the Michelangelo of his age. Under Urban VIII in the 1620s and 30s he had Rome to himself.
Then the bell towers. The ones he designed for the façade of St Peter's cracked the structure beneath, and in 1646 a new and hostile pope ordered the south tower pulled down. It was the great humiliation of his life, and it took Innocent X's own commission for the Four Rivers Fountain to end it. Modern scholarship largely exonerates him — the fault lay in foundations laid by someone else decades earlier.
In 1665 Louis XIV summoned him to Paris to redesign the Louvre. The designs were rejected. He went home and carved the king's portrait bust instead, which is the better outcome for everyone.
His rival Francesco Borromini — stranger, more inventive, far less charming — built much of the same city in opposition to him. Baroque Rome is the argument between them.
