Malagasy mythology is rooted in oral history and has been transmitted by storytelling, notably the Andriambahoaka epic, including the Ibonia cycle. At least 6% of Madagascar are adherents of the religion, which is known as Fomba Gasy, and surveys show it is likely at least half practice some aspects of it. Adherence to Fomba Gasy is high amongst the Sakalava people, as they are reluctant to convert to faiths of foreign origin.
