Much more famous than Durante was Fabio Colonna, or, as he is more generally called, Fabius Columna (Plate IX), who was born at Naples in 1567. His father was a well-known littérateur. Fabio Colonna’s profession was that of law, but he was also well acquainted with languages, music, mathematics and optics. He tells us in the preface to his principal work that his interest in plants was aroused by his difficulty in obtaining a remedy for epilepsy, a disease from which he suffered. Having tried all sorts of prescriptions without result, he examined the literature on the subject, and discovered that most of the writers of his time merely served up the results obtained by the ancients, often in a very incorrect form. So he went to the fountain head, Dioscorides, and after much research identified Valerian as being the herb which that writer had recommended against epilepsy, and succeeded in curing himself by its use. This experience convinced Colonna that the knowledge of the identity of the plants described by the ancients was in a most unsatisfactory condition, and he set himself to produce a work which should remedy this state of things. This book was published in 1592, under the name of ‘Phytobasanos,’ which embodies a quaint conceit after the fashion of the time. The title is a compound Greek word meaning “plant torture,” and was apparently employed by Colonna to explain that he had subjected the plants to ordeal by torture, in order to wrest from them the secret of their identity. But it must be confessed that Colonna himself is by no means free from error, as regards the names which he assigns to them. The great feature of the ‘Phytobasanos,’ however, is the excellence of the descriptions and figures. The latter are famous as being the first etchings on copper used to illustrate a botanical work (Text-figs. 46 and 105). They were an advance on all previous plant drawings, except the work of Gesner and Camerarius, in giving, in many cases, detailed analyses of the flowers and fruit as well as habit drawings. We owe to Colonna also the technical use of the word “petal,” which he suggested as a descriptive term for the coloured floral leaves[16]. By means of his wide scientific correspondence, Colonna kept in touch with many of the naturalists of his time, notably with de l’Écluse and Gaspard Bauhin.
