Philip Larkin’s poem beginning “Seventy feet down” is the second poem in a triptych of works titled “Livings.” In this poem, the “living” described seems to be that of a lighthouse keeper, who looks down on the sea far beneath him. Immediately, then, one of the themes suggested by the poem seems to be isolation.  The speaker is isolated because the lighthouse is probably in some isolated location (perhaps even out on an island, surrounded by the sea). The speaker is also isolated because of his extremely lofty location, not only far above the sea but also distant from other forms of life, human or otherwise. Finally, the speaker is isolated as well because he seems to be the only occupant of the lighthouse. No other occupant is mentioned or even hinted at. Thus the poem seems to deal with a theme – alienation – that is quite typical of Larkin’s work.

The speaker of the poem is mainly a distant observer of energetic action taking place beneath him.  He is not the initiator of, or participant in, any energetic action of his own.  When he exclaims, “Running suds, rejoice!” (5), the exclamation only seems to emphasize, by contrast, his own lack of movement and his own apparent lack of joy. The same pattern is repeated with another exclamation at the end of the second stanza: “Creatures, I cherish you!” (10). Earlier he had addressed the sea itself; now he addresses the creatures who survive in the sea by clinging to rocks. Both exclamations, however, serve only to emphasize the speaker’s distance from the things he describes.

The atmosphere of the poem literally darkens, as does its tone. The speaker is connected to the outside world only tangentially, through technology:

Radio rubs its legs,

Telling me of elsewhere . . . (14-15)

Even the news the speaker hears from the radio is news connected to his job. It isn’t as if he listens to chat shows or takes pleasure in broadcast music. His job defines his life, his very existence, in ways that are truer for him even than for most people. At night, all he can see is snow falling, like moths, as the beam of light from the lighthouse travels around in the sky over waters that are now “Leather black” (25). Both the darkness and the emphasis on winter help imply, again, the speaker’s lonely life. The speaker eats alone and, as the poem ends, sees lit-up ocean liners moving ever farther away from him – one last example of the theme of loneliness.
