This manuscript is a composite manuscript containing three main texts and some miscellaneous notes. It was made in Italy in the 15th century, probably at or for the Aragonese Library in Naples. It is a collection of texts about Greek and Roman history and learning.

The contents are as follows:

Flyleaves: Some notes, poems, etcetera, in Latin and Greek (italic hand) on two vellum fly-leaves

ff. 1v-2r: Two miniatures (see “Illumination”)

f. 2v: Note that seems to be a list of chapters in Coluccio Salutati’s De seculo et religione, beginning with Mundus est campus diaboli and ending with Laqueus animarum parens

ff. 4r-34v: Epistola ad nepotes de utilitate studii librorum gentilum by Saint Basil, translated by Leonardo Aretino

ff. 34v-37r: Description of the Sibyls

ff. 37v-43v: Nomina Ofhciorum et Dignitatum Urbis Romae ac Omcialium (a text on the officials, functions and institutions of the Roman empire)

ff. 44v-45v and on the final fly-leaf: Greek alphabet and miscellaneous jottings

The texts main texts are described separately under MS 120/ff. 4r-34v; MS 120/ff. 34v-37r; and MS 120/ff. 37v-43v.

The hand is Italian minuscule, the ink being very yellow. The small capitals are either red or green, and the rubrics are in square capitals, the words being alternately lake green or gold. The notes are in various other hands.

There are three sectional initials on ff. 4r, 6v, and 37v, elaborately floriated in blue, lake, and green, and two miniatures in watercolour. There is also a sketch in ink on the verso of the final fly-leaf, which resembles the second miniature of Pallas.
