Another early French herbal, very similar to the Arbolayre, was published under the name of ‘Le Grant Herbier.’ The origin of the text of this book has been the subject of some discussion. Choulant regarded it as derived from the Ortus Sanitatis, but an Italian authority, Signor Giulio Camus, has discovered two fifteenth-century manuscripts in the Biblioteca Estense at Modena, which have thrown a different light on the subject. One of these is the work commonly called ‘Circa instans,’ while the other is a version of the Grant Herbier; on comparing the two, Signor Camus concluded that the French manuscript was obviously derived from Circa instans. A version of the latter, differing somewhat from the Modena manuscript, was printed at Ferrara in 1488, and other editions appeared later. The figures which illustrate the Grant Herbier seem to have been derived from those of the Ortus Sanitatis rather than those of the Herbarius. The work is of special interest to British botanists, since it was translated into English and published, in 1526, as the ‘Grete Herball,’ a book which will be discussed at length in the following chapter. Another work, which appeared with reduced copies of the familiar illustrations from the German Herbarius, was the ‘Liber de arte distillandi de Simplicibus’ of Hieronymus Braunschweig (1500). In this book, the method of distilling herbs, in order to make use of their virtues, was described in considerable detail, with drawings of the apparatus employed. 5. THE HORTUS SANITATIS. [Illustration: Text-fig. 8. “Leopardus” [Ortus Sanitatis, Mainz, 1491].] The third of the fundamental botanical works, produced at Mainz towards the close of the fifteenth century, was the ‘Hortus,’ or as it is more commonly called ‘Ortus Sanitatis,’ printed by Jacob Meydenbach in 1491. It is in part a modified Latin translation of the German Herbarius, but it is not merely this, for it contains treatises on animals, birds, fishes and stones, which are almost unrepresented in the Herbarius. Nearly one-third of the figures of herbs are new. The rest are copied on a reduced scale from the German Herbarius, and the drawing, which is by no means improved, often shows that the copyist did not fully understand the nature of the object he was attempting to portray. As an example of a wood-cut, which has lost much of its character in copying, we may take the Dodder (cf. Text-figs. 80 and 77).
