Lingua Aegyptiaca Restituta (Egyptian Language Restored) was a 1643 work about the Coptic language by the Jesuit scholar Athanasius Kircher. It followed his 1636 volume Prodromus Coptus sive Aegyptiacus (The Coptic or Egyptian Forerunner), the first ever published grammar of Coptic. Lingua Aegyptiaca Restituta was dedicated to the Holy Roman Emperor Ferdinand III and published in Rome by Herman Scheuss.
