At this I turned and saw in front of me,
beneath my feet, a lake that, frozen fast,
had lost the look of water and seemed glass.
. . .
And as the croaking frog sits with its muzzle
above the water, in the season when
the peasant woman often dreams of gleaning.
so, livid in the ice, up to the place
where shame can show itself, were those sad shades,
whose teeth were chatttering with notes like storks'.
