Codex MA 592 of the Biblioteca Civica di Bergamo is an illustrated herbal written by Antonio Guarnerino da Padova in 1441. A complete transcription of the text (an Italian translation of "De viribus herbarum" by Macer Floridus) and small reproductions of the illustrations have been published in 2000 (“Herbe Pincte”, G.Silini, G.Polimeni ed.).
The manuscript includes a beautiful self-portrait of Guarnerinus, appropriately holding a plant and a brush. The face of the figure was unluckily altered by a later hand.
