Analysis of Convalescence

From out the dragging vastness of the sea,
Wave-fettered, bound in sinuous, seaweed strands,
He toils toward the rounding beach, and stands
One moment, white and dripping, silently,
Cut like a cameo in lazuli,
Then falls, betrayed by shifting shells, and lands
Prone in the jeering water, and his hands
Clutch for support where no support can be.
So up, and down, and forward, inch by inch,
He gains upon the shore, where poppies glow
And sandflies dance their little lives away.
The sucking waves retard, and tighter clinch
The weeds about him, but the land-winds blow,
And in the sky there blooms the sun of May.
