Ancient Roman farmers' almanacs (in Latin,
menologia rustica) are a type of
Roman calendar providing month-by-month information on conditions and activities pertaining to
agriculture. They were displayed as public
inscriptions. Examples that survived to the modern era are the
Menologium Rusticum Colotianum and the
Menologium Rusticum Vallense, both dating to the period 19–65 AD or 36–39 to the end of the 1st century AD. Both were discovered in the 16th century, but the
Menologium Valense has been lost.
