Book of Enoch
Hoffmann was the author of an acclaimed work on Syriac grammar ("Grammatica syriaca") (1827), and was responsible for a German version of the Book of Enoch based on Richard Laurence's "Book of Enoch the Prophet" called "Das Buch Henoch in vollständiger Uebersetzung". He made important contributions to the second section of the Ersch-Gruber "Allgemeine Encyclopädie der Wissenschaften und Künste".
