Castracane di Ruggero degli Antelminelli

Castracane di Ruggero di Castracane was a Lucchese merchant-banker of the Castracani degli Antelminelli and grandfather of Castruccio Castracani. With his brother Lutterio he inherited, shortly after mid-century, a fortune that included rural estates. His family lived in the Curtis Sancti Martini by the cathedral and participated in Lucca's iron and silver mining.

In his time the firm financed Lucchese spice merchants bound for North Africa in 1270 and grew into one of the great Lucchese banking houses. His son was Gerio, father of Castruccio.
