“At the Nowruz festival in the spring of 488 BCE, the time in which the Persians celebrated their New Year with feasting, partying, and gift-giving, Darius, Great King, King of Kings, King of All Lands, the Achaemenid, sat on his throne in the heart of his palace-city of Persepolis and magnanimously received the homage of his empire.”
