The first fruits of Greek botany.

Theophrastus of Eresus in Lesbos, born about 370 BC, is the author of the most important botanical works that have survived from classical antiquity. He was in turn student, collaborator, and successor of Aristotle. Like his predecessor he was interested in all aspects of human knowledge and experience, especially natural science. His writings on plants form a counterpart to Aristotle’s zoological works.

In the Enquiry into Plants Theophrastus classifies and describes varieties—covering trees, plants of particular regions, shrubs, herbaceous plants, and cereals; in the last of the nine books he focuses on plant juices and medicinal properties of herbs. This edition is in two volumes; the second contains two additional treatises, On Odours and Weather Signs.

In De causis plantarum Theophrastus turns to plant physiology. Books 1 and 2 are concerned with generation, sprouting, flowering and fruiting, and the effects of climate. In Books 3 and 4 Theophrastus studies cultivation and agricultural methods. In Books 5 and 6 he discusses plant breeding; diseases and other causes of death; and distinctive flavors and odors. The Loeb Classical Library edition is in three volumes.

Theophrastus’ celebrated Characters is of a quite different nature. This collection of descriptive sketches is the earliest known character-writing and a striking reflection of contemporary life.

Inductive zoology.

In History of Animals Aristotle analyzes “differences”—in parts, activities, modes of life, and character—across the animal kingdom, in preparation for establishing their causes, which are the concern of his other zoological works. Over 500 species of animals are considered: shellfish, insects, birds, fish, reptiles, amphibians, and mammals—including human beings.

In Books I–IV, Aristotle gives a comparative survey of internal and external body parts, including tissues and fluids, and of sense faculties and voice. Books V–VI study reproductive methods, breeding habits, and embryogenesis as well as some secondary sex differences. In Books VII–IX, Aristotle examines differences among animals in feeding; in habitat, hibernation, migration; in enmities and sociability; in disposition (including differences related to gender) and intelligence. Here too he describes the human reproductive system, conception, pregnancy, and obstetrics. Book X establishes the female’s contribution to generation.

The Loeb Classical Library edition of History of Animals is in three volumes. A full index to all ten books is included in Volume Three.

Aristotle’s biological corpus includes not only History of Animals, but also Parts of Animals, Movement of Animals, Progression of Animals, Generation of Animals, and significant parts of On the Soul and Parva Naturalia. Aristotle’s general methodology—“first we must grasp the differences, then try to discover the causes” (HA 1.6)—is applied to the study of plants by his younger co-worker and heir to his school, Theophrastus: Enquiry into Plants studies differences across the plant kingdom, while De Causis Plantarum studies their causes. In the later ancient world, both Pliny’s Natural History and Aelian’s On the Characteristics of Animals draw significantly on Aristotle’s biological work. The only work by a classical author at all comparable to Aristotle’s treatises on animals is Xenophon’s On Horses (included in Volume VII of the Loeb edition of Xenophon).
