Shadows of a Thousand Years

As Gene Wolfe has observed, the workings of Narrativium and the Morphogenetic Field are not limited to the usual constraints of causality:
When Stelarc dons his Laser eyes...

...and his bioengineered ears...

...and his supplementary hands, he is (all unawares) recapitulating the Perseus myth cycle; with its supplementary Fetch Quests where Perseus gallivants around to obtain the trappings of heroism -- the wingèd sandals and the Glove of Power and the Star Wand --

"You seem to be experiencing some cross-talk or bleed-through from Creatures of Light and Darkness", said tigris.

"Did you watch the Lars von Trier adaptation last night on the Riddled Channel?" Another Kiwi wondered. "Eight hours long but he captured Zelazny's aesthetic exactly."

"...Stelarc is also creating ripples in the morphogenetic field," I said, pressing on and undeterred, "which propagate backwards to trouble the dreams of 16th-century engravers. I am not sure where the shaggy trousers with the pelvic-thrusty wings come from. Perhaps they are part of Stelarc's transhumanism performance which he has not yet perfected."

Meanwhile AK was calibrating the time-machine extension to the Dream Machine so as to inspect the troubled dreams of those engravers and woodcut artists. "The hero, once suitably attired and armed, is supposed to be slaying Medusa, innee?" he vouchsafed. "That does not look like a Medusa." 
"He's chasing Ann Althouse," I said; "that's good enough for government work."

Commentator ITTDGY argues that "close enough" is preferable to "good enough", and he has the backing of Goofle NGram:

I favour "good enough" because shut up that's why.
