One of the 800 acquired 'codices' was a 13th century paper manuscript, containing scholia on the Ilias. On the pages of that manuscript had been glued for illustration 51 parchment fragments with 58 scenes from the Ilias. After the removal of these pieces of parchment, Mai discovered on the reverse of the pictures the original writing, about 800 verses of the Ilias, in a majuscule that is based on the ancient Roman uncials. These fragments, known as the 'Codex Ambrosianus Pictus', or 'Ilias Picta', or in English the 'Ambrosian Iliad', (Biblioteca Ambrosiana, Cod. F. 205 Inf.), were once part of a large-scale illustrated manuscript of Homer's Iliad, which was made ca. 500 in Constantinople or Alexandria. Together they are the oldest surviving manuscript illustrations of the Ilias. Angelo Mai was the first to present them to the learned world in this edition of 1819. § Mai collected from different manuscript in the Ambrosian Library also scholia upon the Odyssea, made by several ancient grammarians. At the end Mai added also 4 fragments of a text of the first century B.C. grammarian Didymus Alexandrinus, 'De lignorum mensuris et marmoribus vel 'Peri tôn marmarôn kai pantoiôn xulôn metrêseôs'' (On the measurement of marble and all kinds of wood); their source is the Greek mathematician Heron of Alexandria, and the text is now known as Didymus' Fragment 68. (B.K. Braswell, 'Didymos of Alexandria: Commentary on Pindar (..) and a critical catalogue of Didymos' Works', Basel 2017, p. 101)) § The discovery of the Homeric scenes of the 'Codex Ambrosianus Pictus', and their printed reproduction in 1819 is a landmark of Homeric study. The Italian scholar Angelo Mai, 1782-1854, was librarian of the 'Bibliotheca Ambrosiana' at Milan from 1811 till 1819. He published from manuscripts held by his Library the correspondence of Marcus Aurelius and Fronto, portions of speeches of Cicero and Symmachus, and scholia and illustrations from the famous Ambrosian manuscript of Terentius (1814-1815). From the Library's Greek manuscripts Mai published part of a speech of Isaeus, an unknown portion of Dionysius of Halicarnassus (1816), and the illustrated fragments of the Iliad, and the scholia on the Odyssea (1819). His best discovery is the Vatican palimpsest with large portions of Cicero's lost treatise 'De Republica' (1822)) (Provenance: On both boards the gilt stamp of the Scottish 'Society of writers to the Signet') (Collation: pi-2pi2; a-o2, chi-23chi2, 1 - 41-2) (Photographs on request) (Heavy book, may require extra shipping costs)
