In this series of The Essay, five leading cultural voices choose a great work of art and talk about a small, under-appreciated aspect of the piece that carries great meaning for them.Art historian and author of The Story of Art Without Men, Katy Hessel draws our attention to the spine as a symbol of feminine strength and survival in Frida Kahlo's Broken Column. No matter how ambitious and brave she was in her painting, life was a constant battle: in love, in her physicality, and her struggle to be taken seriously as a woman and as an artist. Kahlo was stunted by her life – from her operations to her heartbreak, her miscarriage to her constant fight to be heard – Broken Column is a message to us that justice will come; life will be reborn.Producer:Mohini Patel
