Yeah, Arabic too. My bad. I was thinking about Greeks, and Khwarizmi wrote his algebra book al-jibr in medieval times circa AD 700 or 800. So I assumed that Arabic carried the heritage of Greeks before the Renaissance.
Khwarizmi was Persian, not Arabic.
Citation? The Islamic contribution to philosophy and mathematics is impressive but Arabs were always marginal. Many, many Persians, Greeks and other Christians and converts but very few Arabs of any note.
