After having been preserved for centuries at Hohenburg Abbey, the manuscript of "Hortus Deliciarum" passed into the municipal library of Strasbourg about the time of the French Revolution. There the miniatures were copied by Christian Moritz Engelhardt and published by Cotta in Stuttgart in 1818. The text was copied and published by Straub and Keller between 1879 and 1899 including some coloured copies from Herrad's illustrations made by Wilhelm Stengel. Thus, although the original perished in the burning of the libraries of the Protestant seminary and the city of Strasbourg during the siege of 1870 in the Franco-Prussian War, we can still form an estimate of the artistic and literary value of Herrad's work.
