Kathleen Jessie Raine (14 June 1908 – 6 July 2003) was a British poetess, critic and scholar, writing in particular on William Blake, W. B. Yeats and Thomas Taylor. Known for her interest in various forms of spirituality, most prominently Platonism and Neoplatonism, she was a founder member of the Temenos Academy. Raine noted that poetry was deeply ingrained in the daily lives of her maternal ancestors: “On my mother’s side I inherited Scotland’s songs and ballads…sung or recited by my mother, aunts and grandmothers, who had learnt it from their mothers and grandmothers… Poetry was the very essence of life.”
