"A massive guardian statue stands at the Gate of All Nations in Persepolis, the ceremonial heart of the Achaemenid Empire, located in present-day Iran. Commissioned by King Xerxes I in the 5th century BCE, this gate once received envoys from across the empire during New Year festivities. Carved from limestone, the figure features a bull’s body, eagle’s wings, and a human head—symbolizing power, guardianship, and royal dignity. Drawing inspiration from the Assyrian lamassu yet showcasing Persian elements, it exemplifies the empire’s majesty. Although weathered by time, the sculpture still powerfully conveys the artistry and authority of ancient Persia"
