A square riddle -- by Sylvia Plath

Metaphors     by Sylvia Plath (1932-1963)

I'm a riddle in nine syllables,
An elephant, a ponderous house,
A melon strolling on two tendrils.
O red fruit, ivory, fine timbers!
This loaf's big with its yeasty rising.
Money's new minted in this fat purse.
I'm a means, a stage, a cow in calf.
I've eaten a bag of green apples,
Boarded the train there's no getting off.

This 9 x 9 square first appeared in Crossing the Water (Faber and Faber, 1971).
