Note 26 — Chapter VI

The best short account of the Albigenses is to be found in vol. i. of H.C. Lea's Histoire de L'Inquisition au moyen âge, Paris, 1903. This, the French translation, is superior to the English edition as it contains the author's last corrections, and a number of bibliographical notes. The Adoptionist theory is stated in the introduction to F.C. Conybeare's Key of Truth, Oxford, 1908. The Chanson de la Croisade Albigeoise, P. Meyer, Paris, 1875, 2 vols., is indispensable to students of the subject. In these works will be found much of the extensive bibliography of the heresy and crusade.
