Origin of "Every dog has his day"?

Where did this phrase come from?

[Askance]

30 seconds worth of Googling came up with this:

According to the medieval Dutch scholar Erasmus, the saying came about as a result of the death of the Greek playwright Euripides, who in 405 B.C. was mauled and killed by a pack of dogs loosed upon him by a rival. Thus the saying is usually taken to mean that even the most lowly person will at some time get revenge on his oppressor, no matter how powerful the man may be. The Greek biographer Plutarch recorded the proverb for the first time in ‘Moralia’ (A.D. c. 95) rendering it as ‘Even a dog gets his revenge,’ and Richard Taverner included the first version in English - ‘A dogge hath a day’ - centuries later in his ‘Proverbes’ or Adages’ (1539).

The more familiar form dates from the 18th century, and Peter Pindar’s (John Wolcot’s) Odes of Condolence:

Thus every dog at last will have his day,
He who this morning smiled, at night may sorrow;
The grub today’s a butterfly tomorrow.

Be Sirius, sturmhauke.

And forget ye not the version as penned by the Bard:

Let Hercules himself do what he may,
The cat will mew and dog will have his day.
