the Jews in Twelfth-Century Rome: Papal Attitudes toward Biblical Judaism and Contemporary

Friedberg compiled complete editions of the Decretum, the Quinque antiquae compilationes,
and Raymond of peñafort’s Liber extra decretalium, and i have used these for this study.
Also invaluable have been Gratian, ‘Concordia discordantium canonum’, Corpus iuris can-
onici, ed. e. Friedberg, Vol. 1 (Leipzig, 1879), Gregory ix, pope, ‘Liber extra decretalium’,
Corpus iuris canonici, ed. e. Friedberg, Vol. 2 (Leipzig, 1881), pp.5–928, and the Quinque
compilationes antiquae, ed. e. Friedberg (Leipzig, 1882). A reliable, if early, edition which i

lack of nineteenth- and twentieth-century editions of other important thirteenth-century
texts of formal canon law concerned with heretics and Jews has often meant reliance on
fifteenth- and sixteenth-century editions. Here catalogues such as John Oates, A Catalogue
of the Fifteenth-Century Printed Books in the University Library, Cambridge (Cambridge,
1954), have been invaluable.
With respect to conciliar legislation, including Church councils held in the south ofFrance during the period of the Albigensian Crusade, the standard collected edition used
by historians remains Mansi’s Sacrorum conciliorum nova et amplissima collectio, published
in the eighteenth century and based on the earlier collections of editors such as that of
Labbé. There are also a number of much more recent editions and studies of conciliar legis-
lation pertaining in particular to the Lateran Councils of the period, for example, Decrees of
the Ecumenical Councils, Vol. 1: Nicaea I to Lateran V, ed. n. Tanner (London, 1990), and
Jacques Berlioz, Identifier sources et citations, L’Atelier du médiéviste 1 (Turnhout, 1994).
