Theophrastus
Theophrastus (
Greek Θεόφραστος,
372"
287 BC), a native of
Eressos in
Lesbos, was the successor of
Aristotle in the
Peripatetic school. His given name was
Tyrtamus, but he later became known by the nickname "Theophrastus", given to him, it is said, by Aristotle to indicate the grace of his conversation. He released the first recorded
message in a bottle in order to show that the
Mediterranean Sea was formed by the inflowing
Atlantic Ocean.
According to some sources, Theophrastus's father was named Messapus, and was married to a woman named Argiope and was the father of Cercyon -- but, this is not certain.
After receiving his first introduction to
philosophy in Lesbos from one Leucippus or Alcippus, he proceeded to
Athens, and became a member of the Platonic circle. After
Plato's death he attached himself to
Aristotle, and in all probability accompanied him to
Stagira. The intimate friendship of Theophrastus with
Callisthenes, the fellow-pupil of
Alexander the Great, the mention made in his will of an estate belonging to him at Stagira, and the repeated notices of the town and its museum in the History of Plants, are facts which point to this conclusion.
Aristotle in his will made him guardian of his children, bequeathed to him his library and the originals of his works, and designated him as his successor at the
Lyceum on his own removal to
Chalcis.
Eudemus of Rhodes also had some claims to this position, and
Aristoxenus is said to have resented Aristotle's choice.
Theophrastus presided over the Peripatetic school for thirty-five years, and died in
287 BC. Under his guidance the school flourished greatly — there were at one period more than 2000 students — and at his death he bequeathed to it his garden with house and colonnades as a permanent seat of instruction.
Menander was among his pupils. His popularity was shown in the regard paid to him by
Philip,
Cassander and
Ptolemy, and by the complete failure of a charge of impiety brought against him. He was honoured with a public funeral, and "the whole population of Athens, honouring him greatly, followed him to the grave" (
Diog. Laërt.).
From the lists of the ancients it appears that the activity of Theophrastus extended over the whole field of contemporary knowledge. His writing probably differed little from the Aristotelian treatment of the same themes, though supplementary in details. He served his age mainly as a great popularizer of science. The most important of his books are two large botanical treatises, On the
History of Plants, in nine books (originally ten), and
On the Causes of Plants, in six books (originally eight), which constitute the most important contribution to botanical science during antiquity and the middle ages; on the strength of these works some call him the "father of
Taxonomy". We also possess in fragments a
History of Physics, a treatise
On Stones, and a work
On Sensation, and certain metaphysical
Airoptai, which probably once formed part of a systematic treatise. He made the first known reference to the phenomenon of
pyroelectricity, noting in 314 BC that the mineral
tourmaline becomes charged when heated. Various smaller scientific fragments have been collected in the editions of
JG Schneider (1818–21) and
F. Wimmer (1842–62) and in
Usener's
Analecta Theophrastea.
His book
The Characters deserves a separate mention. The work consists of brief, vigorous and trenchant delineations of moral types, which contain a most valuable picture of the life of his time. They form the first recorded attempt at systematic
character writing. The book has been regarded by some as an independent work; others incline to the view that the sketches were written from time to time by Theophrastus, and collected and edited after his death; others, again, regard the
Characters as part of a larger systematic work, but the style of the book is against this. Theophrastus has found many imitators in this kind of writing, notably
Hall (1608),
Sir Thomas Overbury (1614–16),
Bishop Earle (1628) and
Jean de La Bruyère (1688), who also translated the
Characters.
