Giovanni Boccaccio, the Renaissance author and poet, began his
in 1360. The text is a mythography, or a mythological encyclopedia, in which the author assembles, arranges, and explains the tangled myths and legends of antiquity. Each book of the text is prefaced by a diagrammatic genealogical tree tracing the family lines of the figures discussed in the following section, such as this multicolored genealogical tree that prefaces Book IV. The names in the circles in the tree indicate those figures whose progeny appear in this same tree. This manuscript of the Genealogia deorum gentilium was produced ca. 1385-1387 for Coluccio Salutati, an important Florentine bibliophile and humanist scholar.
