P. Labbe, G. D. Mansi, etc., _Sacrorum conciliorum nova et amplissima collectio_ (Paris, 1901-13), esp. vol. xxii, 1166-1225; vol. xxiii, 1225-1268; vol. xxiv, 1269-1299; vol. xxv, 1300-1344; vol. xxvi, 1344-1409._ For papal bulls between 1198 and 1304 see A. Potthast, _Regesta Pontificum Romanorum_ (Berlin, 1874 _et seq._). Important documents relating to the Dominican order are in Ripoll et Brémond, _Bullarium ordinis S. Dominici_ (8 vols., Rome, 1737 _et seq._). The Constitutions of the Emperor Frederick II are in J. L. A. Huillard-Bréholles, _Historia diplomatica Friderici Secundi_ (Paris, 1852-61). III HISTORIES OF THE INQUISITION There are two useful histories of comparatively early date: J. Marsollier, _Histoire de l’Inquisition_ (Cologne, 1693). P. à Limborch, _Historia Inquisitionis_ (Amsterdam, 1692). The English version is _History of the Inquisition_ (tr. S. Chandler, London, 1731). The latter is used in this book except when the _Liber sententiarum_, only printed in the original, is referred to. Limborch’s, although avowedly a propaganda work, is still of value, because it was based on the treatises of inquisitors, making particularly full use of Eymeric, and it is easy to make proper allowance for the avowed bias. In 1817 appeared the first version (a French translation) of the great work on the Spanish Inquisition by J. A. Llorente under the title, _Histoire critique de l’Inquisition d’Espagne_. The original Spanish text was not published till 1822. Only the introduction and first four chapters are relevant to the mediæval Inquisition. English writers have been mainly interested in the Spanish Inquisition, as founded by Ferdinand and Isabella, and in the Inquisition in Portugal. English seamen and traders suffered at their hands, either in the Peninsula or its dependencies, in the sixteenth and seventeenth centuries. See, for example, _English Merchants and the Spanish Inquisition in the Canaries_ (Royal Historical Society, ed. L. de Alberti, A. B. Wallis Chapman, 1912); R. Dugdale’s _A Narrative of popish cruelties; or a new account of the Spanish Inquisition_ (1680) in _Harleian Miscellany_, vol. vii, p. 105; J. Stevens, _The Ancient and Present State of Portugal ... containing ... A curious Account of the Inquisition_ (London, 1705). Later English writers show a similar strongly Protestant bias, _e.g._ F. B. Wright, _A History of Religious Persecution from the Apostolic to the Present Time; and of the Inquisitions of Spain, Portugal and Goa_ (1816); W. H. Rule, _History of the Inquisition_ (London, 1868). Only the first nine chapters of the last-named book are concerned with the Middle Ages. All previous works were superseded by the monumental labours of the American historian, H. C. Lea, in his _Superstition and Force_ (Philadelphia, 1866; 4th ed., 1892). _A History of the Inquisition of the Middle Ages_ (New York, 1887).
