What is "ducetius"

Ducetius (died 440 BCE) was a Hellenized leader of the Sicels and founder of a united Sicilian state and numerous cities. It is thought he may have been born around the town of Mineo. His story is told through the Greek historian Diodorus Siculus in the 1st century BCE, who drew on the work of Timaeus. He was a native Sicilian, but his education was Greek and was very much influenced by Greek civilization in Sicily. He is sometimes known by the Hellenized name of Douketios.
