OWN is paying tribute to Maya Angelou, late friend of the network’s founder, Oprah Winfrey, with five hours of programming on Sunday.

The marathon includes four programs in which the trailblazing poet and memoirist was prominently featured: The Oprah Winfrey Show, a two-part episode of Super Soul Sunday, Oprah’s Master Class, and the premiere of Oprah Winfrey’s Legends Ball.

“I’ve been blessed to have Maya Angelou as my mentor, mother/sister, and friend since my 20’s,” Winfrey said after Angelou died Wednesday at the age of 86. “She was there for me always, guiding me through some of the most important years of my life. The world knows her as a poet but at the heart of her, she was a teacher. ‘When you learn, teach. When you get, give’ is one of my best lessons from her.

“She won three Grammys, spoke six languages and was the second poet in history to recite a poem at a presidential inauguration,” Winfrey continued. “But what stands out to me most about Maya Angelou is not what she has done or written or spoken, it’s how she lived her life. She moved through the world with unshakeable calm, confidence and a fierce grace. I loved her and I know she loved me. I will profoundly miss her. She will always be the rainbow in my clouds.”
