T.S. Eliot, born on September 26, 1888, was a key literary figure of the 20th century, known for his critique of contemporary culture and his poetry. His work often explores themes of decay and renewal, using allusions to myths like the Holy Grail and figures like the Sibyl and Tiresias to illustrate the despair of post-war society. 'The Waste Land' reflects disillusionment and spiritual emptiness, intertwining personal narratives with historical and mythological references.
