‘Das půch der natur’ is slightly later as regards the date of publication, having been printed by Hanns Bämler at Augsburg in 1475. It seems to have been very popular, for it passed through six or seven editions before the end of the fifteenth century. A very large number of manuscripts of ‘The Book of Nature’ exist, as many as eighteen being preserved in the Vienna Library and seventeen at Munich. The text is a compilation from old Latin writings, and is said to have been translated into German as early as 1349. The portion dealing with plants consists of an account of the virtues of eighty-nine herbs with their Latin and German names. The chief interest of the work, from our present point of view, lies in the fact that it contains the earliest known botanical wood engraving (Plate III). We shall return to this subject in Chapter VII. 2. THE HERBARIUM OF APULEIUS PLATONICUS. Another very early book based on classical writings, especially those of Dioscorides and Pliny, was the ‘Herbarium’ of Apuleius Platonicus. This little Latin work is among the earliest to which the term “Herbal” is generally applied. A herbal has been defined as a book containing the names and descriptions of herbs, or of plants in general, with their properties and virtues. The word is believed to have been derived from a mediæval Latin adjective “herbalis,” the substantive “liber” being understood. It is thus exactly comparable in origin with the word “manual” in the sense of a hand-book. Four early printed editions of the Herbal of Apuleius Platonicus are known, all of which appear to have been based on different manuscripts. The earliest was published in Rome late in the fifteenth century, from a manuscript discovered by Joh. Philippus de Lignamine, physician to Pope Sixtus IV. Nothing is definitely known concerning the author, but it is conjectured that he was a native of Africa, and that his book may date from the fifth century, or possibly even the fourth. The work undoubtedly had a career of many centuries in manuscript before it was printed. [Illustration: Text-fig. 1: “Plantago” = Plantain [Herbarium Apuleii Platonici, ? 1484].] Various extant manuscripts of the Herbarium are illustrated with coloured drawings of the crudest description, which are found on comparison to be identical in many different examples, and to have been reproduced, in a degraded form, when the book was printed. The original figures, from which the drawings in the different manuscripts were copied, must date back to very early times. They probably represent, as Dr Payne has pointed out, a school of botanical draughtsmanship derived from late Roman art.
