Sonnet (Millay)
hack carriages
A hack is a hired carriage for funerals—cheap, impersonal transport. The repetition "hack following another hack" makes years into identical rented vehicles.
empty hearse
The hearse is "driven empty" to hide that no one cared enough to attend. The fear isn't death but dying unmourned.
deaf, triumphant
Dead ears are "triumphant" because they can't hear mockery. Death as victory over humiliation, not tragedy.
leap into the sun
The only moment of vitality in the whole poem—"leap"—is immediately followed by burial. Life as brief interruption of death.
ultimate hill
Cemetery on a hill, but "ultimate" makes it final destination. She wants to skip to being "abandoned"—past caring, past being cared about.
