The present study attempts an ecocritical approach to Rose Tremain's memoirs Rosie: Scenes from a Vanished Life (2018). Ecocriticism is concerned with the literary representation of man-environment relationship; it is a literary theory that engages diverse disciplines of humanities and science. Based on this propensityforinterdisciplinarity, this study draws on Greek mythology; the Gaia-Prometheus myth; science, James Lovelock's Gaia hypothesis; and ecology, the dichotomous concepts of human-nature connectedness and ecophobia. Dividing the different generations in the memoirs into two, the elders and the youngster, the study investigates how these generationsrelate to nature; which generation enjoys an interconnected stance to nature, and which one holds an ecophobic attitude. What nature represents to these generations, andthe effect of their different allegiances with it on their lives are approached. The study also traces the failures and successes of these members and shows to what extent they are conditioned by their different stances toward nature.
