Are the statements of Ibn al-Jawzi, Ibn Hazm and Ibn Taymiyyah enough to declare Ijma' (consensus) on the sphericity of earth

It was reported in fatawa collection of Taymiyyah , that Abu-al-Hussain Ahmed ibn Jaafar ibn al-Munady said that there is a consensus about the sphericity of earth; fatawa collection (25/195). He also said in another fatwa that Ibn-Hazm , and Ibn al-Jawzi said that there is a consensus too; fatawa collection (6/586). About what Ibn Hazm said, that there is a consensus is reliable, because he mentioned that in one of his book (Al-Fasl fi al-Milal wa al-Ahwa' wa al-Nihal 2/78 "الفصل في الملل والأهواء والنحل") Could this be considered an Islamic consensus, or some level of consensus?
