"This great celebration was probably offered in honor of the new heir. It was set on a date of astronomical interest, 9.18.1.2.0, or November 15, A.D. 791, a day when Venus rose as Evening Star, and a date that may have been chosen to assure that the young dynast would be a great warrior. A broad cross-section of the Maya hierarchy attends his celebration at court."
