Ethiopian thinker who, hiding in a cave from persecution, examined all religious claims by the “light of reason” – recorded in the Hatata (1667). Its authorship has been debated since 1920: Conti Rossini attributed it to the missionary Giusto da Urbino, who supplied the manuscript in the 1850s; Claude Sumner, Getatchew Haile and others defend Ethiopian authorship. The question remains open.

    Known only from the two Hatatas themselves: Zera Yacob’s treatise says he taught the sons of his patron Habtu, among them Walda Heywat, at whose request he wrote, and Walda Heywat presents his own treatise as his teacher’s continuation; the authenticity of both texts has been disputed since Conti Rossini (1920).

Works

  • 1667Hatata (Inquiry)

    An autobiographical inquiry: all religions claim truth, but only reason can decide what God truly wills. (Its authorship has long been debated.)

Position

Zera Yacob’s Hatata (“inquiry”) of 1667, written at the request of his pupil Walda Heywat, records his reflections. Seeing Christians, Muslims and Jews condemn one another, he asked how to know who is right, and answered: by the light of reason God gives every human. God exists and is good, but scriptures are human works and must be tested; rules that contradict reason and the order of creation, such as monastic celibacy or the subordination of women, cannot be God’s will. All humans are equal. Its authorship has been disputed since 1920, when Carlo Conti Rossini attributed it to the Capuchin missionary Giusto da Urbino, who had supplied the manuscript in the 1850s; Eugen Mittwoch added linguistic arguments in 1934. Claude Sumner and others defended Ethiopian authorship from the 1970s, the historian Anaïs Wion has since renewed the doubts, and scholars remain divided.

Life & context

Zera Yacob was born in 1599 near Aksum in Ethiopia to a poor farming family and received a traditional church education. When King Susenyos favored Catholicism, he was denounced and fled, living for about two years in a cave near the Tekezé river. He then settled at Enfraz, where he worked for a wealthy man named Habtu, married and taught. According to the text, he died in 1692.
