WALDO. The leader of those early Protestants, the Yaudois, or Waldenses, was Peter Waldo, a merchant of Lyons, who, in the XII. century, denied transubstantiation, and translated the Gospels into French. Peter Waldo, Esq., the author of a Commentary on the Liturgy of the Church of England (1731—1803), is said to have been a lineal descendant of his illustrious namesake.
