Remember
Silent land
Victorian euphemism for death, borrowed from Longfellow's popular 1839 poem 'A Psalm of Life.' Rossetti expects her reader to catch the literary reference.
Half turn
The physical hesitation of leaving—one foot out the door, body twisted back. She's describing the moment before death, not after.
Counsel then or pray
After death, advice and prayers won't reach her. This contradicts Catholic doctrine about prayers for the dead—Rossetti's Anglo-Catholic faith believed they could.
Darkness and corruption
Literal physical decay of the body in the grave. She's acknowledging what Victorians usually avoided: corpses rot.
Vestige of thoughts
The conditional 'if' matters—she's uncertain whether consciousness survives death at all. Unusual doubt for a religious poet.
Forget and smile
The volta reverses everything. She gives him permission to move on, prioritizing his happiness over being remembered.
