Diomedes Cato was an Italian-born lutenist and composer who spent his career in Poland and Lithuania, born between 1560 and 1565 near Treviso, possibly at Serravalle. His Protestant family fled Italy to escape the Inquisition around 1565 and settled in Kraków, where Cato received his entire musical education. He was hired as a lutenist to the court of King Sigismund III Vasa in 1588, a position he held until 1593, and in 1593–94 accompanied the king on a journey to Sweden, where his playing won wide acclaim. He continued working in Poland into the early seventeenth century and died in Gdańsk in 1627.

Diomedes Cato was the leading lutenist-composer of the Polish-Lithuanian Commonwealth, blending late Renaissance Italian technique with the emerging early Baroque style and incorporating Polish folk idioms into his fantasias and dances. His music, preserved largely in German and English manuscript anthologies, represents one of the most significant contributions of the Polish court tradition to the broader European lute repertoire.
