One of the contemporaries of Dioscorides, Gaius Plinius Secundus, commonly called the Elder Pliny, should perhaps be mentioned at this point, although he was not a physician, nor does he deserve the name of a philosopher. In the course of his ‘Natural History,’ which is an encyclopædic account of the knowledge of his time, he treats of the vegetable world. He refers to a far larger number of plants than Dioscorides, probably because the latter confined himself to those which were of importance from a medicinal point of view, whereas Pliny mentioned indiscriminately any plant to which he found a reference in any previous book. Pliny’s work was chiefly of the nature of a compilation, and indeed it would scarcely be reasonable to expect much original observation of nature from a man who was so devoted to books that it was recorded of him that he considered even a walk to be a waste of time! The writings of the classical authors, especially Theophrastus and Dioscorides, dominated European botany completely until, in the sixteenth century, other influences began to make themselves felt. As we shall see in the following chapter, the earliest printed herbals adhered closely to the classical tradition. CHAPTER II THE EARLIEST PRINTED HERBALS (FIFTEENTH CENTURY) 1. THE ENCYCLOPÆDIA OF BARTHOLOMÆUS ANGLICUS AND ‘THE BOOK OF NATURE.’ After the invention of printing, a very active period of book production followed, during which many works, which had previously passed a more or less lengthy existence in manuscript, were put into circulation in print, contemporaneously with books actually written at the time. The result is that a number of the “incunabula,” as printed books of the fifteenth century are technically called, are far more ancient, as regards the matter which they contain, than the date of their publication would seem to suggest. This characteristic is illustrated in the Encyclopædia of Bartholomæus Anglicus, and in Konrad von Megenberg’s ‘Das půch der natur,’ which were perhaps the earliest printed books containing strictly botanical information. The former work, which was first printed about 1470, was compiled by a monk, sometimes called Bartholomew de Glanville, who flourished in the thirteenth century. The title by which it is generally known is ‘Liber de proprietatibus rerum.’ One of the sections of which it is composed is concerned with an account of a large number of trees and herbs, arranged in alphabetical order, and is chiefly occupied with their medicinal properties. It also includes some theoretical considerations about plants, on Aristotelian lines. An English translation, which was printed by Wynkyn de Worde before the end of the fifteenth century, is interesting as containing the very primitive botanical wood-cut reproduced in Text-fig. 19.
