The old man’s profile
Black marble, jutting white hook
Eagle eye — and beak

The old man’s profile
Darkness, even in full sun
All crags and shadow

The old man’s profile
Stone silent, fixed in sorrow
Gazing toward the end

The old man’s profile
Stone silent, fixed in wisdom
Gazing toward the end

or

The old man’s profile
Stony silence, dignified
Gazing toward the end
