Holy Saturday has not inspired an outpouring of excellent poems, but here is a fine one from Denise Levertov called Ikon: The Harrowing of Hell. It begins as so:
“Down through the tomb’s inward arch
He has shouldered out into Limbo
to gather them, dazed, from dreamless slumber:
the merciful dead, the prophets,
the innocents just His own age and those
unnumbered others waiting here
unaware, in an endless void He is ending
now, stooping to tug at their hands,
to pull them from their sarcophagi,
dazzled, almost unwilling. Didmas,
neighbor in death, Golgotha dust
still streaked on the dried sweat of his body
no one had washed and anointed, is here,
for sequence is not known in Limbo;
the promise, given from cross to cross
at noon, arches beyond sunset and dawn.”
