Федериго да Монтефельтро
Berlinghieri's work was originally to be dedicated to the Ottoman Sultan Mehmed II. When the sultan died in 1481, Berlinghieri dedicated it to Federico da Montefeltro, the Duke of Urbino. Unfortunately, the duke died before the final edition was printed. Additionally, manuscript copies of the book were dedicated to Lorenzo de' Medici and Federigo da Montefeltro and individual copies of the printed edition were dedicated to the Ottoman Sultan, at that time Bayezid II and his half-brother Cem Sultan.³
