GUILLAUME RONDELET.
Rondelet greatly surpassed Gesner, Belon, and Salviani, in the extent of his knowledge as an ichthyologist; and although his figures, being only wood-cuts, are inferior in beauty to the copperplate-engravings of the last of these authors, they are yet more correct in the characteristic details. His work is entitled De Piscibus Marinis Libri XVIII., in quibus vivæ piscium imagines expositæ sunt, and was published at Lyons in 1554. A second part appeared in 1555, under the name of Universæ Aquatilium Historiæ Pars Altera, cum veris ipsorum Imaginibus. The first part treats of marine animals, including the cetacea, turtles and seals, the mollusca, and the crustacea. In the second part, shells, insects, zoophytes, and fresh-water fishes, are described. These objects, although not methodically arranged, are often placed in such a manner as to indicate that the author had some idea of generic affinity. The anatomical details which he presents are pronounced by Cuvier to be frequently correct; but his descriptions, it must be granted, are inferior to the figures, which are truly surprising for the period at which he lived. In reference to the fishes of the Mediterranean this work is indispensable, and, indeed, to the ichthyologist generally it is one of the most important that exists. The descriptions and figures have been copied by Gesner, in his work De Aquatilibus; while Ray, Artedi, and Linnæus, have obviously profited by them.
Rondelet, the son of an apothecary, was born at Montpellier on the 27th September 1507. Being originally of a very infirm constitution, he was judged incapable of performing a part in active life, and, accordingly, when his father's fortune was distributed, he received a sum merely sufficient to procure his admittance into a convent. As he grew up, however, he improved in strength, and having no affection for a monastic life, he commenced his studies at the age of eighteen, and finished his general education at Paris, where he was supported by his elder brother. Having resolved to embrace the medical profession, he returned in 1529 to his native city, and afterwards settling at Pertuis, a small village in Provence, he began to practise; but not meeting with success in the healing art, he endeavoured to procure subsistence by setting up a grammar-school. This expedient also failing, he went again to Paris in order to improve his knowledge of the Greek language, and, being unwilling to burden his brother any longer, became tutor to a young nobleman. Some time after, he removed to Maringues, in Auvergne, where he again entered upon practice, and in 1537 received a medical degree at Montpellier. The following year he married a young lady endowed with many estimable qualities, but destitute of fortune; and, as his brother was dead, this alliance increased his difficulties. However, he settled finally at the place of his birth; and, being assisted by his wife's sister, began to extend his acquaintance, and succeeded so well in his profession, that, in 1545, he was appointed professor of medicine in the university.
He also obtained the office of physician to the Cardinal of Tournon, whom he accompanied on his missions in France, Italy, and the Low Countries, of which occasions he eagerly availed himself to increase his knowledge of natural history. Returning once more to his usual place of residence he established an anatomical theatre, at which he lectured several hours daily to a numerous audience. His passion for dissection was so strong, that he opened one of his own children after death, and this circumstance has naturally enough given rise to the opinion, that he must have been a man destitute of sensibility; which, however, does not appear to have been the case. His wife having died in 1560, he soon procured another, poor and handsome like the first. While on a journey to Toulouse he was attacked by dysentery, occasioned by eating too many figs, and he died at Realmont, whither he had gone to visit a patient. His death happened on the 30th July 1566, in the fifty-ninth year of his age.
He was a man of very small stature, but robust and active. At the age of twenty-five he gave up the use of wine and spirits, from an apprehension of gout; but he compensated for his abstemiousness in these articles by indulging his appetite for fruit and pastry. Although he had acquired considerable sums of money in the practice of his profession, he expended them in the gratification of his taste for building, and in various acts of generosity; so that he left very little behind him.
