Easton's Bible Dictionary: M. G. Easton, M.A., D.D.
"the chief man of the island" of Malta (Acts 28:7
), who courteously entertained Paul and his shipwrecked companions for three days, till they found a more permanent place of residence; for they remained on the island for three months, till the stormy season had passed. The word here rendered "chief man" (protos) is supposed by some to be properly a Maltese term, the official title of the governor.
