Etymology : 1530s, “workmanship, the making of anything by craft or skill,” from Middle French artifice “skill, cunning” (14th century), from Latin artificium “a profession, trade, employment, craft; making by art,” from artifex (genitive artificis) “craftsman, artist,” from stem of ars “art” + facere “to make, do”.
