The right bank of the River Danube in eastern Croatia was settled by people of the Vučedol culture in the early third millennium B.C. This leading cultural formation between 3000 and 2500 B.C. strongly influenced the other cultures of the time and has left noticeable marks on the entire heritage of Europe. It coexisted with the Sumerian period in Mesopotamia, the building of pyramids in Egypt, and the early layers of Troy. The Vučedolians were the first people to have mastered time—the first culture that made a calendar! The first astronomers to read the secrets of the heavens. It is shameful how little we today know of the images above our heads... Pit 6, which was later re-numbered as Grave 3, was dug 4 meters away from the edge of the lowest floor of the Vučedol culture. In the grave, or rather, tomb, a total of eight bodies were found. Especially noteworthy among the large number of ceramic finds is the terrine, the most artistically decorated one of all those found so far in the Vučedol culture. On the night of 9 March 2889 B.C., having just passed through the Pleiades, the planets Venus and Mars found themselves in a conjunction visible from Earth as a close approach or "posture of love". Pictographically marked on the terrine are the oldest definite dates in prehistory:
• Mars enters the Pleiades (7 February 2889 B.C.)
• Venus enters the Pleiades (22 February 2889 B.C.)
• The planets enter into conjunction (9 March 2889 B.C.) and Encke's Comet passes between them.
