In the "Egg" there is not only the form of the lines, which gradually expand and then taper downwards, but there is also a great amount of similitude—the literary egg being compared to a real egg, and the poet to the nightingale that laid it. There is also a remarkable involution in form—the last line succeeding the first, and so on; and this alternation of the verses is compared to the leaping of fawns. The Axe or Hatchet is apparently a sort of double axe, being nearly in the form of wings; and is supposed to be a dedicatory inscription written to Minerva on the axe of Epeus, who made the wooden horse by which Troy was taken.

The ancient riddles seem to have been generally of a descriptive character, and not to have turned upon quibbles of words, like those of the present day. They more corresponded to our enigmas—being emblematic—and in general were small tests of ingenuity, some being very simple, others obscure from requiring special knowledge or from being a mere vague description of things. Of the learned kind were doubtless those hard questions with which the Queen of Sheba proved Solomon, and those with which, on the authority of Dius and Menander, Josephus states Solomon to have contended with Hiram. The riddle of Samson also required special information; and the same characteristics which marked the early riddles of Asia, where the conceit seems to have originated, is also found in those of Greece. Who could have guessed the following "Griphus" from Simonides of Ceos, without local knowledge, or with it, could have failed,

"I say that he who does not like to win
The grasshopper's prize, will give a mighty feast,
To the Panopeiadean Epeus."

This means, we are told, that when Simonides was at Carthea he used to train choruses, and there was an ass to fetch water for them. He called the ass "Epeus," after the water-carrier of the Atridae; and if any member of the chorus was not present to sing, i.e., to win the grasshopper's prize, he was to give a chœnix of barley to the ass. Well might Clearchus say "the investigation of riddles is not unconnected with philosophy, for the ancients used to display their erudition in such things."

Somewhat of the same character is found in the following from Aristophanes.

People. How is a trireme a "dog fox?"

Sausage Seller. Because the trireme and the dog are swift.

People. But why fox?

Sausage Seller. The soldiers are little foxes, for they eat up the grapes in the farms.

The simplicity of some of the ancient riddles may be conjectured from the fact that the same word "griphus" included such conceits as verses beginning and ending with a certain letter or syllable.
