Masupa is the hidden creator of an Efe (Bambuti) narrative recorded by Paul Schebesta: 'In the beginning there was only Masupa. He was quite alone, and had neither wife nor brother.' He brought forth three children — two sons, ancestors of the Pygmies and of the neighbouring farmers, and one daughter — and dwelt unseen in a great hut by the river, from which the sound of hammering and forging could always be heard. He failed his children in nothing; they lived in ease, without toil, and the daughter's only duty was to set water and firewood at his door, under the one command that none should ever seek to see him. Moved by curiosity, she hid and glimpsed his richly adorned arm; Masupa, enraged, withdrew down the river, leaving his children tools and weapons but bequeathing work, painful childbirth and death, and was never seen again. The narrative is a distinct strand of the Efe record: some retellings assign the hidden god's role to Tore, and modern scholarship cautions that Schebesta's assembly of the Efe names into one creator reflects his monotheistic framework, so the equation is recorded here as an observation about naming rather than as kinship. His three children remain unnamed in the sources, so no genealogical line can be drawn from him.
