Tomaso Missaglia, (1415-1468г.), Milan, Italy.
The gunsmith's family originated in the town of Missaglia on the shores of Lake Como. Later, Tomaso and his descendants took the surname Nergoli, as evidenced by the tombstone in the church of Santa Maria presso San Satiro in Milan, which lists two surnames. Petraggiolo, Tomaso's father, was also a gunsmith, but we know little about him.
The gunsmiths' workshop was located on Porta Romana Street, for which they paid rent to the Duke of Milan in the form of one helmet of sallets per year.
In 1435, Filippo Maria Visconti granted Tomaso Missaglia a noble title, and in 1450 he was exempted from paying taxes.
The Milan archives contain a sufficient amount of information about orders to the master, about the payment of taxes, and other issues related to the Missaglia family. In 1469, Tomaso Missaglia died and was buried in the church of Santa Maria in Milan. The only work of the master has been preserved and is exhibited in the Museum of the Royal Hunt and Arms in Vienna. Baron de Cosson pointed out the strong similarity of this armour with the statue of Richard Beauchamp, Earl of Warwick, in the church of St. Mary in Warwick and with the painting of St. George by Mantegna in the Venetian Academy.
