Augustan Obelisk from the Circus Maximus
Piazza del Popolo
The Flaminio Obelisk was brought from Heliopolis by Augustus in 10 BC and set up on the spina of the Circus Maximus in Rome as a monument to the conquest of Egypt and a dedication to the sun. It is 23.70 meters high and made of Aswan granite. It dates to the 13th century BC and has hieroglyphs from both Seti I and his son Rameses II. It was discovered in 1587 and then moved to the Piazza del Popolo. In 1818, copies of Egyptian lions were added by Valadier.
It was one of two carried off by Augustus in 10 BC with identical inscriptions - the other being the obelisk at the Obelisk of Horologium Augusti.
