The poem 'Echo' is written in 3 Isometric Sestets, the tripartite structure can be seen as an allusion to the Three Fates of Greek mythology - Clotho, Lachesis, and Atropos - who spin, measure, and cut the thread of life - Each sestet symbolically aligns with a stage of this mythic cycle: the first with Clotho (beginnings and longing), the second with Lachesis (measuring dreams and imagined reunion), and the final stanza with Atropos (the severance of hope and the acceptance of loss) - Rossetti’s structural echo of this classical triad lends the poem a fatalistic undercurrent, suggesting that love, memory, and grief are bound to an inescapable thread of destiny
