It took three hefty gods to chain and rivet the Titan Prometheus to Mt Caucasus. In Aeschylus’ play, Prometheus Bound (430BC), the gods of strength (Kratos), violence (Bia) and black-smithing (Hephaestus) fix Prometheus to the rock.
Kratos says to Hephaestus, “Now drive the adamantine wedge’s stubborn edge straight through his chest with your full force.”
“Alas, Prometheus,” says Hephaestus shortly before exiting the scene, “I groan for your sufferings.”
Defying Zeus, Prometheus gave us fire. Yet, in a speech delivered to the choir of visiting ocean spirits, chained painfully to the rock, Prometheus declares that he also gave us writing. He gifted us the stringing up of letters with which to hold all things in memory.
From Prometheus, we are able to write things down so we will not forget them. Over space and time the things we have written persist.
Do not struggle with your writing. Do not feel it has left you. In a brave and selfless act writing was given to you by a noble hero. It is yours for the taking.

Reasons to Keep Writing 
It seems fitting that both fire and writing should come from the same source. Both are soul-stuff and light the world, in a way.
