Bacon's Essays, and Wisdom of the Ancients

It is elegantly fabled by Tythonus, that being exceedingly beloved by Aurora, she petitioned Jupiter that he might prove immortal, thereby to secure herself the everlasting enjoyment of his company; but through female inadvertence she forgot to add, that he might never grow old; so that, though he proved immortal, he became miserably worn and consumed with age, insomuch that Jupiter, out of pity, at length transformed him to a grasshopper.

Explanation.—This fable seems to contain an ingenious description of pleasure; which at first, as it were in the morning of the day, is so welcome, that men pray to have it everlasting, but forget that satiety and weariness of it will, like old age, overtake them, though they think not of it; so that at length, when their appetite for pleasurable actions is gone, their desires and affections often continue; whence we commonly find that aged persons delight themselves with the discourse and remembrance of the things agreeable to them in their better days. This is very remarkable in men of a loose, and men of a military life; the former whereof are always talking over their amours, and the latter the exploits of their youth; like grasshoppers, that show their vigor only by their chirping.
