Final answer:
The moral of Christina Rossetti's 'Goblin Market' focuses on the dangers of temptation and the redemptive power of sisterly love and sacrifice, while also offering commentary on Victorian social norms.
Step-by-step explanation:
The poem Goblin Market by Christina Rossetti is replete with themes and can be interpreted on multiple levels. The central moral appears to be a cautionary tale about temptation and the importance of sisterly love and sacrifice. The sisters, Laura and Lizzie, encounter goblins who peddle luscious, forbidden fruits. Laura succumbs to temptation and falls into a state of decline, while Lizzie resists and eventually saves Laura by enduring abuse from the goblins without falling into their trap. Through Lizzie's selfless action, Rossetti seems to suggest that love and virtue triumph over temptation and evil.
Additionally, there are undercurrents of a critique of Victorian era social norms, particularly around the market economy, sexual exploitation, and the redemption and resilience of the fallen woman. These interpretations grant the poem a rich depth and enduring relevance, well beyond the didactic moral of the narrative surface.
