30 Horizon Line when Orion Falls 08,000 BC 09,000 BC 10,000 BC – Skewed 11,000 BC 12,000 BC 13,000 BC 14,000 BC 15,000 BC – Parallel 16,000 BC 17,000 BC – Skewed 18,000 BC 19,000 BC 20,000 BC 21,000 BC 22,000 BC The horizon line limits the time of painting to between 10,000 BC and 17,000 BC at the extremes. 2,000 AD 30 15,000 BC Lascaux.19thpsalm.org

31 Visibility of Orion's Belt Between 8,350 BC and 13,200 BC Orion's belt is always below the horizon - 12,900 BC: 1 of 3 stars barely visible at horizon - 13,200 BC: 2 of 3 stars barely visible at horizon  Hence, the painting must be earlier than 13,200 BC and later than 17,000 BC. Later than 9,000 BC the horizon line is quite skewed Lascaux.19thpsalm.org
