Fabio m
Italian, Spanish, and Portuguese: from the old Roman family name Fabius, said to be a derivative of faba bean. Members of this family were prominent in republican Rome. The most famous of them was Quintus Fabius Maximus (d. 203 BC), the Roman general who harassed the invader Hannibal but never joined battle, giving his name to the phrase ‘Fabian tactics’, implying a policy of gradual attrition as opposed to full-scale confrontation. The name was also used among the early Christians: St Fabius (d. 300) was a Roman soldier beheaded at Caesarea in Mauretania under the Emperor Diocletian.
