A combined work of two original manuscripts translated into English from two seperate works in Italian of the same manuscripts on the arts; yet highly Biblical based that was altered in 18th century from the original work in 15th century.That now has been combined together to bring new life in to it a old work of writtings on the arts as well on painting of composition and with the tail end of it has the poets that is used for art works. For nothing is left out but jointly put together for a new book out of two old ones.
