The most famous in story are the Shield of Achilles described by Homer, of Hercules, described by Hesiod, and of
Æneas described by Virgil.
Other famous bucklers described in classic story are the
following: That of
(son of Poseidon or Neptune), a crayfish, symbol of prudence. Cadmos and his descendants, a dragon, to indicate their descent
from the dragon's teeth. Etcocles (4 syl.), one of the seven
heroes against Thebes, a man scaling a wall.
(4 syl.), a cock. Menetaos, a serpent at his heart: alluding
to the elopement of his wife with Paris. Parthenopocos, one of
the seven heroes, a sphinx holding a man in its claws. Ulysses, a dolphin. Whence he is sometimes called Delphinosemos.
Servius says that the Greeks in the siege of Troy had, as a
rule, Neptune on their bucklers, and the Trojans Minerva.
It was a common custom, after a great victory, for the victorious
general to hang his buckler on the walls of some temple.
The clang of shields.
When a chief doomed a man to death, he struck his shield with the
blunt end of his spear, by way of notice to the royal bard to begin the
death-song. (See Aegis.)
Cairbar rises in his arms,
The clang of shields is heard.
Ossian: Temora, f.
