Felt was also sometimes used to cover the bodies of quadrupeds. According to Aristotle[656], the Greeks clothed their molles oves either with skins or with pieces of felt; and the wool became gray in consequence. The Persians used the same material for the trappings of their horses (Plutarch, Artax. II. p. 1858. ed. Stephani).

The loose rude coverings for the feet called Udones were sometimes made of felt, being worn within the shoes or brogues of the rustic laborers[657].

In concluding this investigation it may be proper to observe, that, although πῖλος originally meant felt, and more especially a skull-cap made of that manufacture, it was sometimes used, at least by the later Greek authors, by an extension of its meaning, to denote a cap of any other material. Thus Athenæus (lib. vi. p. 274. Casaub.) speaking of the Romans, says, that they wore about their heads πίλους προβατείων δερμάτων δασεῖς, i. e. “thick caps made of sheep skins.”
