Forethought
“Of four infernal rivers that disgorge
Into the burning Lake their baleful streams;
Abhorred Styx the flood of deadly hate,
Sad Acheron of sorrow, black and deep;
Cocytus, nam’d of lamentation loud
Heard on the rueful stream; fierce Phlegethon
Whose waves of torrent fire inflame with rage.
Far off from these a slow and silent stream,
Lethe the River of Oblivion rolls
Her wat’ry Labyrinth whereof who drinks,
Forthwith his former state and being forgets,
Forgets both joy and grief, pleasure and pain.”
--John Milton, Paradise Lost
