An unsurpassed Master of knowledge
Claudio Ptolomeo, Egyptian astronomer, mathematician and geographer, from the II century of the Christian era, born in Tolemaida Hermia (High Egypt) and lived and worked in Alexandria. Almost rivalling in his ingenuity the great Hiparco of Nicea and, systematically, hardly surpassed by anybody, possessed the knowledge of antiquity in several scientific fields, extending it in some of them. For astronomers’ use he invented a trigonometry, so complete, that it prevailed throughout the Middle Ages.
A masterpiece of singular beauty
The manuscript which exists in the Biblioteca General e Histórica de la Universidad Literaria de Valencia was ordered to be copied and illustrated by Alphonse the Magnanimous from the library owned by the King in Castel Nuovo of Naples and was passed on to the library of San Miguel de los Reyes. It dates from the XV century, as other copies exist in His Majesty’s Libraries, today in the Paris National Library. The Jesuit priest Jos Fischer, in an article published in the journal "Iberica" alludes to this manuscript and the mention of Greek or Latin manuscripts existent in the Libraries of Rome, London, Milan, Florence, Naples, Vienna, Munich, Venice, Parma, Modena and Nancy. The editions succeed one another from 1475 to 1845.
