CHAP. 45.—RUE.
Rue,[1] too, is generally sown while the west winds prevail,
as well as just after the autumnal equinox. This plant has an
extreme aversion to cold, moisture, and dung; it loves dry,
sunny localities, and a soil more particularly that is rich in
brick clay; it requires to be nourished, too, with ashes, which
should be mixed with the seed as well, as a preservative against
the attacks of caterpillars. The ancients held rue in peculiar
esteem; for I find that honied wine flavoured with rue was
distributed to the people, in his consulship,[2] by Cornelius
Cethegus, the colleague of Quintus Flamininus, after the
closing of the Comitia. This plant has a great liking[3] for the
fig-tree, and for that tree only; indeed, it never thrives better
than when grown beneath that tree. It is generally grown
from slips, the lower end of which is inserted in a perforated[4]
bean, which holds it fast, and so nurtures the young plant
with its juices. It also reproduces itself;[5] for the ends of the
branches bending downwards, the moment they reach the
ground, they take root again. Ocimum[6] is of a very similar
nature to rue, except that it dries with greater difficulty.
When rue has once gained strength, there is considerable difficulty in stubbing it, as it causes itching ulcerations on the
hands, if they are not covered or previously protected by being
rubbed with oil. Its leaves, too, are preserved, being packed
in bundles for keeping.
1. The Ruta graveolens of Linnæus. See B. xx. c. 51. This offensive
herb, though looked upon by the Romans as a vegetable, is now only regarded as an active medicament of almost poisonous qualities.
2. A.U.C. 421.
3. It so happens that it thrives best on the same soil as the fig-tree.
4. This practice has no beneficial effect whatever.
5. This is not the fact; for its branches never come in contact with the
ground.
6. Pliny has derived the greater part of this Chapter from Theophrastus,
Hist. Plant. B vii. c. 5, and Columella, B. xi. c. 3.
