A lunar calendar

"The grandfather clock is an enemy telling me that death runs at my heels.  The clock has a painted face picturing the four seasons; Spring, a child on a sheep-covered hill; Summer, a girl big with child raking hay in a shining meadow; Autumn, a woman blown before a tempest; Winter, an old man with a red face pushing sticks into a fire under a cooking pot slung from a tripod.  There is a painted moon behind, that moves with the days of the month."
