Easton's 1897 Bible Dictionary:

Mason
   an artificer in stone. The Tyrians seem to have been specially
   skilled in architecture (1 Kings 5:17, 18; 2 Sam. 5:11). This
   art the Hebrews no doubt learned in Egypt (Ex. 1:11, 14), where
   ruins of temples and palaces fill the traveller with wonder at
   the present day.
