Where the De Luca surname comes from
De Luca is a patronymic surname: it means “son of Luca.” Medieval records wrote “Antonio de Luca,” meaning Antonio son of Luca, and that “de Luca” stayed with the family. The name comes from the Greek Loukás: perhaps “man from Lucania,” perhaps a name linked to light. It spread widely in the Middle Ages thanks to devotion to Saint Luke the Evangelist.
The cardinal of Venosa
In the 1600s a De Luca born in Basilicata became one of the greatest jurists of his time, and then a cardinal in Rome. He had an idea that seemed revolutionary back then and that we take for granted today. The PDF tells what it was, and who the other cardinal De Luca was.
