What's the origin of the phrase 'One swallow doesn't make a summer'?

This old proverb is listed in several early glossaries, notably Richard Taverner’s transcription of the [Latin] proverbs of Erasmus – Prouerbes or adagies with newe addicions, gathered out of the Chiliades of Erasmus, 1539:

It is not one swalowe that bryngeth in somer. It is not one good qualitie that maketh a man good.

It is interesting that, even in the 16th century, the figurative meaning of the phrase was made explicit.
