Hyacinthe, Pere, ecclesiastical title of Charles Loyson (b. 1827), born at Lyons, entered the Carmelite order. He attracted attention by his preaching at Bordeaux, Perigueux, and (1865-1869) at Paris. The boldness of his views led to his being denounced at Rome for heresy, and in 1870 the Pope relieved him of his monastic vows. His eloquence gave a transient vitality to the latest phase of the Gallican movement in France, a phase which he originated in sympathy with the "Old Catholic" movement. He married an American lady in London in 1872, and, Dean Stanley being his friend, delivered four lectures in London, 1870. In 1893 he delivered a series of addresses in the provinces of France, and transferred his church in Paris to a Dutch body of Dissentient Catholics.
