Illi Persenetesi, (-1677, ?) was a builder in Engaruka.
Illi believed in Animism.
She lived a life of absolute poverty. Eating or sleeping in a safe place was a constant struggle. She belonged to the low caste of the society, and had some friends among the servants, beggars and workers. People saw Illi as cultivated, eager to read and learn when possible, and mastering writing, which she did for friends. She was vigorous, muscular, and had a near perfect body. She was known to be lazy, barely waking up in the morning.
