Venus tablet of Ammisaduqa

The Venus tablet of Ammi-Saduqa (Enuma Anu Enlil Tablet 63) is the record of astronomical positions for Venus, as preserved in numerous cuneiform tablets dating from the first millennium BC. Scholars believe that this astronomical record was first compiled during the reign of King Ammi-Saduqa, the fourth ruler after Hammurabi. Thus, the origins of this text could probably be dated to around the mid-seventeenth century BC (according to the Middle Chronology) despite allowing two possible dates.
