This is the first to appear of the projected volumes of commentary to accompany the texts and translations on Theophrastus of Eresus: Sources for his Life, Writings, Thought and Influence, edited by W.W. Fortenbaugh and others ("FHSG" (Philosophia Antiqua 54); Leiden, Brill, 1992).
It covers the ancient secondary evidence for Theophrastus' views on physiology, zoology and botany; the transmission, reliability and doctrinal content of the reports in the text-and-translation volume are all discussed in detail, and general overviews are provided.
The commentary is an indispensable accompaniment to the text-and-translation volume, and the two together will be an important resource for students of the history of the biological sciences in antiquity.
