“She'd never seen a monster like that before, had never heard of one in all the Lore. When she grappled with the question of what it was, her sharply honed scientifical mind deduced one answer: manbearpig.”

Ch 1
A Canticle for Leibowitz (1959), Fiat Homo
Context: He had never seen a "Fallout," and he hoped he'd never see one. A consistent description of the monster had not survived, but Francis had heard the legends. He crossed himself and backed away from the hole. Tradition told that the Beatus Leibowitz himself had encountered a Fallout, and had been possessed by it for many months before the exorcism which accompanied his Baptism drove the fiend away.
Brother Francis visualized a Fallout as half-salamander, because, according to tradition, the thing was born in the Flame Deluge, and as half-incubus who despoiled virgins in their sleep, for, were not the monsters of the world still called "children of the Fallout"? That the demon was capable of inflicting all the woes which descended upon Job was recorded fact, if not an article of creed.
