Close-up of the quadriga (four-horse chariot) on top of the Brandenburg Gate in Berlin (Germany) at night. The sculpture was produced by Johann Gottfried Schadow in 1793. The word quadriga may refer to the chariot alone, the four horses without it, or the combination. All modern quadrigas are based on the Horses of Saint Mark, a Roman or Greek sculpture which is the only surviving ancient quadriga.Photo credit: ื (Aleph)
