Biography
Mattias pursued an ecclesiastical career, like his brother
Ferdinando de' Medici, the elder son. On 29 May 1629, Grand Duke Ferdinando appointed Mattias governor of Siena, following the death of their aunt and the then governor, Caterina de' Medici.[2]
He arrived in his domain on 27 August and took up residence in the Piazza del Duomo. Spending the bulk of his time in Siena, he was immensely popular among the Sienese.[2] In 1631, he joined the Austrian belligerency in the Thirty Years' War. He took part in the famous battle of Lützen,[3] in November 1632, where he met Sienese General Ottavio Piccolomini.
Upon his return to the grand duchy in 1641, he resumed the reins of Sienese government. He did not stay long, nevertheless, as the
Barberini Pope, entrusting the government of Siena to his brother Cardinal Leopoldo de' Medici for the duration of his absence.[citation needed

Mattias adored the arts, patronising
Volterrano and many other eminent artists. He also loved horse races and was particularly enthusiast of the famous Palio, which he promoted during its early history. While in Germany, he acquired scientific instruments, such as dials, astrolabes and compasses; all of which he later deposited in the Uffizi.[citation needed

In later life, suffering from gout, he pondered re-assuming ecclesiastical garb; however, he fell ill and died in Siena on 11 October 1667 at 54 years of age. He was buried in the Medici tombs in
