Folio 25v. Woad (Isatis tinctoria). Woad has been cultivated throughout Europe since ancient times and was the only available source for blue dye until the end of the sixteenth century. In Medieval times, Tuscany Italy was one of the centers for the cultivation of woad. It was used to dye textiles.
