The contemplative voice of the poem who observes a well and the surrounding environment. The speaker reflects on humanity's limited understanding of the physical world, feeling a deep sense of awe. Recognizing the unfathomable depths hidden within seemingly ordinary scenes, the speaker questions how others can act so casually around such power.

A contained body of water personified as a male neighbor from a different place. Though trapped within human-made boundaries like a glass-lidded jar, the well harbors an abyss-like depth. This deep water hints at the sublime, quiet power of the environment contained within domestic spaces.

The omnipresent, feminine entity encompassing the entire physical world. Described as a stranger residing in a haunted house, she represents a vast mystery. Humans understand her less the closer they attempt to study her, making true comprehension impossible.

The tame greenery planted directly beside the well. Personified as a bold male figure, the grass stands unbothered next to the deep water, displaying a self-assured stoicism. The speaker views this lack of fear as a sign of ignorance rather than genuine courage.

A wild, hardy type of plant growing precariously along the seaside. Also personified as male, the sedge stands on unstable, floorless ground without showing any hesitation. It mirrors the regular grass's unearned confidence but operates in a much more dangerous and unpredictable environment.

A vast, uncontained body of water that acts as a wild parallel to the well. Left genderless by the speaker, the ocean represents the grand and untamable aspects of the physical world. It actively threatens the plants on its shores through erosion and unpredictable whims.
