"It was a custom with Apelles, to which he most tenaciously adhered, never to let any day pass, however busy he might be, without exercising himself by tracing some outline or other,—a practice which has now passed into a proverb. It was also a practice with him, when he had completed a work, to exhibit it to the view of the passers-by in his studio, while he himself, concealed behind the picture, would listen to the criticisms…. Under these circumstances, they say that he was censured by a shoemaker for having represented the shoes with one latchet too few. The next day, the shoemaker, quite proud at seeing the former error corrected, thanks to his advice, began to criticise the leg; upon which Apelles, full of indignation, popped his head out and reminded him that a shoemaker should give no opinion beyond the shoes, —a piece of advice which has equally passed into a proverbial saying."

“The world, and whatever that be which we call the heavens, by the vault of which all things are enclosed, we must conceive to be a deity, to be eternal, without bounds, neither created nor subject at any time to destruction. To inquire what is beyond it is no concern of man; nor can the human mind form any conjecture concerning it.”

“The bird of passage known to us as the cuckoo.”

“It is far from easy to determine whether she has proved to man a kind parent or a merciless stepmother.”
