 The Antemoro were also widely reputed in the pre-colonial period for their astrologers, who would predict the future based on lunar phases.They were known all across Madagascar and acted as advisers at the court of many Malagasy kings, including the celebrated Merina king Andrianampoinimerina, whose Antemoro astrologers advised him and taught him sorabe writing.The pan-Madagascar tradition of the ombiasy is rooted in this element of Antemoro culture.
