It was only in 1823 that Grotefend's discovery was confirmed, when the French archaeologist Champollion, who had just deciphered Egyptian hieroglyphs, was able to read the Egytian dedication of a quadrilingual hieroglyph-cuneiform inscription on an alabaster vase in the Cabinet des Médailles, the "Caylus vase". The Egyptian inscription on the vase was in the name of King Xerxes I, and Champollion, together with the orientalist Antoine-Jean Saint-Martin, was able to confirm that the corresponding words in the cuneiform script were indeed the words which Grotefend had identified as meaning "king" and "Xerxes" through guesswork. The findings were published by Saint-Martin in "Extrait d'un mémoire relatif aux antiques inscriptions de Persépolis lu à l'Académie des Inscriptions et Belles Lettres", thereby vindicating the pioneering work of Grotefend.
