John Freeman’s speaker watches the tide pour into sea caves, beating against rock in a rhythm that feels both violent and alive. That motion becomes a way of describing inner life: the heart and mind are hollow cliffs, full of dark tunnels and unlit thoughts. The incoming tide is emotion itself—restless, pounding, caught between ecstasy and pain—until it fills every space so completely that even old strife goes quiet. The repeated knocking of the waves suggests an unresolved struggle that eventually exhausts itself into silence. There is a strange stillness afterward, as if the wave pulls back carrying something muted. The closing questions ask whether love can ever move through these cold, empty hollows with the same deep, grave, eternal motion. The mood is brooding, resonant, and a little sorrowful, like a cave echoing long after the water has gone.
The Caves — Summary
Like the tide--knocking at the hollowed cliff And running into each green cave as if In the cave's night to keep Eternal motion grave and deep;--
That, even while each broken wave repeats Its answered knocking and with bruised hand beats Again, again, again, Tossed between ecstasy and pain;
Still in the folded hollow darkness swells, Sinks, swells, and every green-hung hollow fills, Till there's no room for sound Save that old anger rolled around;
So into every hollow cliff of life, Into this heart's deep cave so loud with strife, In tunnels I knew not, In lightless labyrinths of thought,
The unresting tide has run and the dark filled, Even the vibration of old strife is stilled; The wave returning bears Muted those time-breathing airs.
--How shall the million-footed tide still tread These hollows and in each cold void cave spread? How shall Love here keep Eternal motion grave and deep?
