Bestiary of Vices and Virtues captures, on the one hand, the influence of the forest environment that shaped Leonardo da Vinci's childhood and future, and on the other, the profuse imagination that always characterized the Renaissance genius. As in the fables of Aesop, La Fontaine, and Prévert, the humanization of animals acts as a reflection of human vices, virtues, and excesses, and invites reflection at a time of delicate natural balance, marked by the threat of extinction of many species. Redmer Hoekstra's illustrations delve into this encounter between two worlds through detailed pencil prints in which the aura of the Renaissance merges with surrealist strokes marked by Escherian influence.
