Abba Pentelewon (c. 470–522) was a Christian monk who is traditionally credited with founding Pentalewon Monastery located on the top of Mai Qoho Hill northwest of Axum in Tigray, Ethiopia. He is one of the members of the group known as the Nine Saints.
In 480 AD Abba arrived in Axum, the first great capital city of Ethiopia, as well as other 9 saints from different parts of the Rome Empire. They were escaping the impositions of the Chalcedonian Council of 451 AD, which had declared their Monophysitism to be a heresy. They contributed greatly to the spread and flourishing of Ethiopian Christianity. They built churches in different parts of ancient Ethiopia, organized Christian centers. They also learned the Ge’ez language that was spoken in Ethiopia and made the first translations of Bible into Ge'ez. They establish many monasteries in the Tigre region and in the area outside Aksum, the most famous of which is Dabra Damo.
