The follow-on is less well known.
...
His acts being seven ages. At first, the infant,
Mewling and puking in the nurse's arms.
Then the whining schoolboy, with his satchel
And shining morning face, creeping like snail
Unwillingly to school. And then the lover,
Sighing like furnace, with a woeful ballad
Made to his mistress' eyebrow. Then a soldier,
Full of strange oaths and bearded like the pard,
Jealous in honor, sudden and quick in quarrel,
Seeking the bubble reputation
Even in the cannon's mouth. And then the justice,
In fair round belly with good capon lined,
With eyes severe and beard of formal cut,
Full of wise saws and modern instances;
And so he plays his part. The sixth age shifts
Into the lean and slippered pantaloon,
With spectacles on nose and pouch on side;
His youthful hose, well saved, a world too wide
For his shrunk shank, and his big manly voice,
Turning again toward childish treble, pipes
And whistles in his sound. Last scene of all,
That ends this strange eventful history,
Is second childishness and mere oblivion,
Sans teeth, sans eyes, sans taste, sans everything.
An older version of this theme is the riddle of the Sphinx. The Great Sphinx of Giza is a famous landmark in Egypt.
The riddle is something like the following, the original being lost to time.
"
Which creature has one voice and yet becomes four-footed and two-footed and three-footed?"
Oedipus solved the riddle.
The Greek sphinx had a different appearance.
The second riddle goes as follows.
"
There are two sisters: one gives birth to the other and she, in turn, gives birth to the first. Who are the two sisters?"
