"Remember your epiphanies on green oval leaves, deeply deep,
copies to be sent if you died to all the great libraries of
the world, including Alexandria?" The Library of Alexandria
was famously the greatest in the ancient world. It was also
famously destroyed in late antiquity, so Stephen's
self-mortifying fantasy is a little over the top. But the
young Joyce actually did give instructions that were only
slightly less pretentious.
So important were his early "epiphanies"
in his ambition to become a great prose artist that Joyce at
one time viewed them as masterpieces, rather than simply
sketches. The editors of a webpage on the epiphanies published
by The James Joyce Centre note that in 1902, "as he was
preparing to leave for Paris, Joyce gave Stanislaus (who was
keeper of the manuscript of the epiphanies) instructions that,
in the event of his death, copies of the epiphanies were to be
sent to all the major libraries of the world, including
the Vatican" (emphasis added). See jamesjoyce.ie/epiphanies.
For several centuries, from the 3rd century BC to the 1st AD,
the Hellenistic library at Alexandria was a great center of
learning, visited by scholars from throughout the
Mediterranean world. The library preserved every single text
it could get its hands on, often by seizing scrolls carried by
visitors to the city, returning copies to them, and keeping
the originals. According to tradition, the library was
destroyed in a great fire, but scholars have not been able to
determine exactly when or how it may have happened.
