Barnacles
Soul as maritime metaphor
Lanier transforms an internal emotional struggle into a sailing journey. The soul becomes a ship, the past becomes physical weight.
Barnacle as psychological burden
Barnacles are not just marine creatures here, but symbolic attachments preventing forward movement. Each 'clingeth and worketh dole'—causing suffering.
Temporal conflict metaphor
The poem frames time as an active antagonist: the Past literally tries to hold back the speaker's forward motion.
