Cornelius Loos

Cornelius Loos, also known as Cornelius Losaeus Callidius, was a Roman Catholic priest, theologian, and professor of theology. He was the first Catholic official to write publicly against the witch trials raging throughout Europe from the 1580s to the 1590s. For this, he was imprisoned and forced to recant; his work was confiscated and suppressed by church officials. His manuscript was lost for almost 300 years. It was discovered in the Jesuit Library of Trier in 1886 by an American historian, George Lincoln Burr.
