We owe lyric poetry to Sappho. Her nuances of personal human feelings exceeded anything that had been written before; she was called the Tenth Muse. If you're into poetry, you should know Sappho. She wrote music-and-dance plays —what we have left is like Hammerstein without Rodgers — and her words have lasted over 2,000 years. Sappho was a musician as well. She introduced the plectrum for lyre playing — we still use it today: the guitar pick.
