Juvenal was an early second-century AD Roman poet. Although little else is known about his life, he is credited with having written sixteen satires. When first published, the satires were divided into five books, and in them Juvenal criticised the beliefs and morals of his contemporaries. Juvenal addresses many of the concerns in second-century Rome in his poems, including the tensions between non-Roman social climbers and Roman citizens, the preservation of existing social class, and the excesses of the Roman citizen class.

All sixteen satires are contained in MS 199. In this volume, each satire begins with an argumenta, in red ink, followed by the text of the satire.

The first satire begins on f. 1r with the Argument: In hac satyra causas primum reddit... The text of the satire begins on the same folio: Semper ego auditor tantum?

The remaining fifteen satires and arguments are found on the following folios:

The last of Juvenal's satires, Satire XVI ends on f. 88r of MS 199 with the line et ventri indulsit non omne legumen. Telos.

Written in a good italic hand, the Argumenta on f. 1r in pale red. Titles are in purple or green capitals, and the initials are plain Roman capitals touched with a thin wash of colour, either blue or lake.

The initial at the beginning is of flat gold and contains a figure like Pan playing a lyre, a helmet and armour beside him, a landscape background, and all in water colour.
