knowledge from Muslim and non-Muslim educators. Hunayn ibn Ishaq was one of the most well-known translators at the institution and was called "the sheikh of the translators, as he mastered the four principal languages of the time: Greek, Persian, Arabic, and Syriac. He was able to translate compositions on philosophy, astronomy, mathematics, medicine, and even in subjects such as magic and oneiromancy. Nonetheless, none of his extant translations credit the House of Wisdom, which questions the legitimacy of whether this place actually was the origin of the Translation Movement. Some of Hunayn's most notable translations were his rendering of "De materia Medica", a pharmaceutical handbook, and his most popular selection, "Questions on Medicine", a guide for novice physicians.
