BOYD, ZACHARY (I585?-1653), Scottish divine, was educated at the universities of Glasgow and St. Andrews. For many years a teacher in the Protestant college of Saumur in France, he returned to Scotland in 1621, to escape the Huguenot persecu tion. In 1623 he was appointed minister of the Barony church in Glasgow, and he was rector of the university in 1634, 1635 and 1645. He bequeathed L20,000 Scots, to the university, besides his library and 12 volumes of mss. In later years he was a staunch Covenanter. His best known works are The Last Battel of the Soul in Death (1629), reprinted with a biography by G. Neil (Glasgow, 1831) ; Zion's Flowers-of ten called "Boyd's Bible" (1644) ; Four Letters of Comfort (1640, reprinted, Edinburgh, 1878).
