The stories of Saint Joachim and Anne and the life of Saint Catherine of Siena

Stained-glass window V30 of Milan Duomo is formed of four columns and concludes at the top with trefoils and a rose window. The work is divided into two parts: the cartoons for the panels found in the lower part of the window are attributed to Giovanni da Monte, created by Corrado de Mochis and Pier Angelo Sesini (1562-67); these tell the story of the life of Joachim and Anna, parents of Mary, a subject narrated in the Apocryphal Gospels that was a popular topic in the late-Mediaeval era. The upper part is dedicated instead to the life of Saint Catherine of Siena and consists of 24 panels, the work of Corrado de Mochis and assistants. In both sections the story unfolds from bottom to top, left to right. The stained-glass window is therefore clearly divided into two sections and the panels are structured in such a way as to appear as if they were two separate stained-glass windows placed inside the same window: they differ in terms of subject and theme, composition, style, and artists.
