Virginia Woolf's 'To the Lighthouse,' published in 1927, is a key work of high modernism that explores themes such as gender roles, the struggle of artists, and the transient nature of life through various symbols. Key symbols include the lighthouse representing truth and goodness, Lily's painting symbolizing the challenges faced by women artists, and the sea and storms reflecting the instability of time and emotions. Critics continue to debate and interpret the novel's symbols, reinforcing its status as a complex and masterfully constructed literary work.
