I don't know what the previous reviewer is talking about; I loved this book. Granted, I am no scholar of Sappho. Although I have read various translations of her poetry in the past, I do not read Greek and cannot comment upon whether Reynolds' research is accurate. However, given her amazing previous work (editing Aurora Leigh, the Penguin Book of Lesbian Short Stories, etc.) I am inclined to trust her (and I like her writing style anyway).
For me, this book was the perfect introduction to Sappho. It includes historical background followed by many of Sappho's fragments in a variety of translations. But that's just the beginning: Reynolds goes on to show how Sappho has been imagined/created by literature up to the present day. She anthologizes a variety of poems, plays, and fictions inspired by Sappho. It is amazing to see how, though so little of her writing survived, she has remained a titaness in our imaginations. Each literary generation has reinvented and recreated her. Reading Jeanette Winterson's amazing story "The Poetics of Sex" (narrated by a modern-day Sappho) fills me with hope and joy at the potential for lesbian creativity that is Sappho's legacy. I also appreciated the inclusion of works of art depicting Sappho through the ages. Although they are in black and white, they are an exquisite visual touch to this beautiful volume (the cover art is amazing as well).
I urge you not to judge this book by one bad review. It is a book to be perused at leisure, to leaf through in times of anxious sorrow and contemplative joy. Buy or borrow a copy and judge it for yourself.
