Parker had a long, prolific career before macular degeneration began stripping him of his precious eyesight. I especially like his etchings-- rich, imaginative works with strong compositions. They take full advantage of the grainy textures and special "look" of the etching medium, something very unusual for the field of illustration.
Parker also made some striking images expressing his political views:
Most people regard eyesight as the crucial requirement for a visual artist, but there are other compensating qualities that can help to offset diminishing sight. One is imagination. Here is Parker's recent painting of a dogfight between a plane and a bug:
I've previously quoted Tennyson's famous poem, Ulysses, which describes the hero's resolve, at the end of a long life of adventure, to set out once again. He rousts his aging comrades to accompany him to see if "some work of noble note may yet be done."
Ulysses admits that old age has robbed his crew of much, yet he glories in what still "abides":
Tho' much is taken, much abides; and tho'
We are not now that strength which in old days
Moved earth and heaven, that which we are, we are;
One equal temper of heroic hearts,
Made weak by time and fate, but strong in will
To strive, to seek, to find, and not to yield.
