Omne Bonum

Omne Bonum (English: Every Good Thing) is a 14th-century encyclopedia compiled in London by James le Palmer (b. before 1327, d. c. 1375).

Entries cover a variety of topics, including theology, natural history, geography, and historical figures, with a particular interest in canon law.

'In this work,' he says, '[can be found] all good materials heretofore scattered widely both in canon law and in various other books or authoritative volumes .

In addition to the Vulgate, his key sources include canon laws collections such as the Decretum and their commentators (particularly Hostiensis and 'the Archdeacon' Guido de Baysio); Guillaume Durand's Speculum iudiciale; William of Pagula's Summa summarum; Bartholomeus Anglicus' De proprietatibus rerum; Thomas of Ireland's florilegium Manipulus florum; and the pseudo-Aristotelian Secretum Secretorum.

He also cites many common theological and philosophical authorities, including Augustine, Ambrose, Gregory, Aristotle, Cicero, Avicenna, and Averroes.
