The family to which Ibn Yunus belonged played an important role in the cultural life of Islamic Egypt, between the third and fifth centuries after Hijra. Ibn Yunus Al-Muarekh was the grandson of a friend of Al-Imam Al-Shafii, and a narrator of the Hadith of the Prophet. He was also the father of the famous Egyptian astronomer Ali Ibn Yunus.
Ibn Yunus Al-Muarekh was well acquainted with Egypt and its people, and was familiar with the country's history. He divided the history of Egypt into two parts; the first was the major history, which was concerned with the Egyptians, and the second was the minor history, which was concerned with what travelers who came to Egypt had to say about it. However, none of the historical works of Ibn Yunus is extant. It seems that some of the works still existed until the ninth century after Hijra, because Al-Maqrizi frequently referred to the works, and quoted Ibn Yunus, in many of his writings.
There is always hope that a copy of his valuable works, may be found among the millions of Arabic manuscripts, in the world. His work was described by a poet, who wrote: By tracing them back you resurrected their dead, as if they had never died, by recording their origin.
