Roman Farmer's calendar. Rome, Museo della Civiltà Romana, inv. M.C.R. n. 3485 Each side bears the names of three months of the year. For each month we can see, starting from the top: the number of days in it; the day on which the Nones (the day of the Moon's first quarter) falls; the duration of the day and night expressed in hours; the sign of the zodiac; the protecting divinity; work to be attended to in the fields; and the most important festivities.
