See, in the chequered pavement opposite,
Suppose the artist made a perfect rhomb,
And next a lozenge, then a trapezoid—
He did not overlay them, superimpose
The new upon the old and blot it out,
But laid them on a level in his work,
Making at last a picture; there it lies.
So, first the perfect separate forms were made,
The portions of mankind; and after, so,
Occurred the combination of the same.
