When we scry with an arsenic mirror, poison
blackens the brightest suns,
fouls the fairest fortunes,
and smudges the saintliest souls.
Glass gassed with our own
undigested venom gives a glimpse
of the godless ghosts we're twinned
to in the womb.
Arsenic mirror (a highly unscientific definition) - an old method of detecting arsenic poisoning. If the ignited gasses from the stomach of a corpse smudged a cool glass or plate, arsenic was present. Anyone else watching Taboo?
