: It is widely accepted that all civilizations have used a calendar. To the question:
“Did the Aegean, the Minoan and the Mycenean Civilization use a calendar?” the answer
is yes. So, have any of those calendars survived and been examined scientifically, and, if so,
what kind of calendars are they?" Presumably, most calendars were created on perishable
material and thus did not survive. But there are also imperishable materials such as
ceramics and stone which were used for the recording of the passage of time.
Surviving Megalithic constructions such as Avebury, Newgrange, Stonehenge and others may
have functioned partly as calendars. In this paper, after a short discussion on the different
types of calendars used in prehistoric times, a unique Aegean lunisolar calendar carved on a
block of Aegean marble (dated 2750-2300 BCE) is examined and decoded. This unusual
artifact was found in 1964 on the Aegean Island of Keros by the archaeologist Chr. Dumas
(1968), who named it “The Dove Vase”. This unusual artifact was found in 1964 on the
