the proportions of the several parts of the human body: as,
twice round the thumb is once round the wrist; twice round the wrist is
once round the neck; twice round the neck is once round the waist; once
round the fist is the length of the foot; the two arms extended is the
height of the body; six times the length of the foot, or eighteen
thumbs, is also the height of the body.

Again, the thumb, the longest toe, and the nose should all be of the
same length. The index finger should measure the breadth of the hand and
foot, and twice the breadth should give the length. The hand, the foot,
and the face should all be the same length. The nose should be one-third
of the face; and, of course, the thumbs should be one-third the length
of the hand. Gerard de Lairesse has given the exact measurements of
every part of the human figure, according to the famous statues of
"Antin[:o]us,[TN-98] "Apollo Belvidere," "Hercul[^e]s," and "Venus
de'Medici."

=Polycrates= (4 _syl._), tyrant of Samos. He was so fortunate in
everything, that Am'asis, king of Egypt, advised him to part with
something he highly prized. Whereupon, Polycr[)a]t[^e]s threw into the sea
an engraved gem of extraordinary value. A few days afterwards, a fish
was presented to the tyrant, in which this very gem was found. Amasis
now renounced all friendship with him, as a man doomed by the gods; and
not long after this, a satrap, having entrapped the too fortunate
despot, put him to death by crucifixion. (See FISH AND THE
RING.)--_Herodotus_, iii. 40.

=Polyd'amas=, a Thessalian athlete of enormous strength. He is said to
have killed an angry lion, to have held by the heels a raging bull and
thrown it helpless at his feet, to have stopped a chariot in full
career, etc. One day, he attempted to sustain a falling rock, but was
killed and buried by the huge mass.

Milo carried a bull, four years old, on his shoulders through the
stadium at Olympia; he also arrested a chariot in full career. One day,
tearing asunder a pine tree, the two parts, rebounding, caught his hands
and held him fast, in which state he was devoured by wolves.

=Polydore= (3 _syl._), the name by which Belarius called Prince Guiderius,
while he lived in a cave in the Welsh mountains. His brother, Prince
Arvir[)a]gus, went by the name of Cadwal.--Shakespeare, _Cymbeline_
(1605).

_Polydore_ (3 _syl._), brother of General Memnon, beloved by the
Princess Calis, sister of Astorax, king of Paph
