Decretum of Gratian

Manuscript (G.37)
The Morgan Library and Museum, New York

Medieval church law defined the degrees of family relationship within which a person might or might not be allowed to marry. Folio 1r of this canon law manuscript of the mid-thirteenth-century shows the Tree of Consanguinity. (Consanguinity: relationship by blood or by a common ancestor.) It is actually signed by the artist in a scroll held by two men at the foot, 'Gautier Lebaube fit larbe' (Gautier Lebaube made the tree').
