This initial begins the first response of the first nocturn of Matins for Ascension week, "Post passionem suam per dies quadraginta apparens eis ..." (After his Passion, during forty days he appeared to them). In this scene of the Ascension, only Christ's feet are visible as his body "disappears" into heaven. One often finds the marginal spaces of medieval manuscripts filled with fanciful creatures or humorous scenes that often mocked or parodied everyday life. Here, a man holds a leash attached to three dogs dressed in elegant costume dancing to the music of a pipe and tabor. Lewis E M 42:15 and 16b are from the same manuscript.
