Sappho brought forth a newly personal, emotionally intimate form of poetic disclosure. She creatively transformed lyric poetry in both technique and style as she moved from the tradition of poetry written from the perspective of gods and muses to one expressing the personal vantage point of the individual.
Tarnas argues that Sappho’s literary innovation constitutes a cosmologically correlated psychological revolution — the birth of the individual as the locus of poetic and emotional truth.
