Here's one view.

And here's another, in Richard Wilbur's version:

FRANÇOIS VILLON: Ballade of the Ladies of Time Past.

O tell me where, in lands or seas,

Flora, that Roman belle, has strayed,

Thais, or Archipiades,

Who put each other in the shade,

Or Echo who by bank and glade

Gave back the crying of the hound,

And whose sheer beauty could not fade.

But where shall last year's snow be found?

Where too is learned Héloïse,

For whom shorn Abélard was made

A tonsured monk upon his knees?

Such tribute his devotion paid.

And where's that queen who, having played

With Buridan, had him bagged and bound

To swim the Seine thus ill-arrayed?

But where shall last year's snow be found?

Queen Blanche the fair, whose voice could please

As does a siren's serenade,

Great Bertha, Beatrice, Alice—these,

And Arembourg whom Maine obeyed,

And Joan whom Burgundy betrayed

And England burned, and Heaven crowned:

Where are they, Mary, Sovereign Maid?

But where shall last year's snow be found?

Not next week, Prince, nor next decade,

Ask me these questions I propound.

I shall but say again, dismayed,

Ah, where shall last year's snow be found?
