She "is considered by many to have been the greatest woman poet of the Heian period". Her legacy includes 242 poems and two kashu.
"Torn between worldly ties and physical desire, Izumi Shikibu left a wealth of passionate love poetry, fueling rumors that purported that she was a femme fatale with numerous lovers besides her two husbands and two princely lovers.":155" - (en.wikipedia.org 11.08.2021)
