St Augustine, De Civitate Dei and De Trinitate, the first with the commentaries of Thomas Waleys (d. 1350) and Nicholas Trevet (d. c. 1334), with additions by Iacopo Passavanti (d. 1357), and Franciscus de Mayronis (d. c. 1325).  The second work has comment by Mayronis only.

Two originally separate but matching volumes, both printed at Lyons by Iohann Koburger, ‘citizen of Nuremberg’ in 1520, the first on 15 Oct., the second on 31 July.

Seventy years after the first printed book, printers could now produce sophisticated page layout (mise en page) such as this, designed to enable reading of the text alongside the relevant commentary.
