Inventor Leo Thrasher, perhaps the last modern-day Renaissance man, builds a machine to throw
him back to Renaissance Italy, where he plans to leave his mark as a painter. Once there,
he’s taken under the wing of Guaracco who views him as a potential rival, but still sees a
use for the time traveler. When Leo’s memory of future wonders begins to fade, Guaracco
pulls 20th-century memories from Leo’s subconscious via hypnotic interviews, somehow even
managing to pull out (among other more mundane things) a working pair of wings for Leo to fly
over 15th-century Florence.
But suppose this me is taken completely out of Twentieth Century
existence—dematerialized, recreated in another epoch. That makes twice in time,
doesn’t it?
