Without a doubt, the 17805 manuscript of the National Library of Spain is one of the richest illuminated examples about the famous epic of Troy’s war that are being kept at that Library, written by the notorious italian lawyer, poet and historian known as Guido delle Colonne. The manuscript arrived to the Library after the Pascual de Gayangos funds were bought at 1899. It was written on parchment paper, showing red ink for the incipit and black ink for the rest of the book. The language used is latin. The manuscript contains ninety three miniatures with high iconographic value, generally on the upper or lower part of the sheets, which are illuminated with various colours, and beatiful initials embossed with burnished gold. Two of the miniatures, corresponding with 3r and 27r sheets, are historiated initials. Also some sheets are beautifully adorned with vegetal decorations around the text
