‘We’re almost there,’ murmured Jacques, ‘because this opening is the hollow peak of the Menelaus crater.’ And, indeed, the tunnel came to an end and they emerged near the Acherusia promontory, not far from the Plinius crater in the Sea of Serenity,

As far as the eye could see a silent, raging sea was rolling with breakers as high as cathedrals. On all sides were cataracts of congealed spume, avalanches of petrified waves, torrents of mute howling, a whole seething tempest compressed and anaesthetised in a single stroke. It extended so far that the eye, confused, lost all sense of proportion, amassing mile upon mile, regardless of the possibilities of distance and time.

J.-k. Huysmans, 1887
