And work with pleasure, while they cheer the eye
With glowing purple of the Tyrian dye:
Or justly intermixing shades with light,
Their colorings insensibly unite
As when a shower, transpierced with sunny rays,
Its mighty arch along the heaven displays;
From whence a thousand different colors rise
Whose fine transition cheats the clearest eyes;
So like the intermingled shading seems
And only differs in the last extremes.
