Yusuf al-Shirbini was a well-educated Egyptian from the eleventh/seventeenth century, thought to originate from the town of Shirbin, then a significant rural center in the eastern part of Delta. Little is known about him--including his social standing and profession--beyond Brains Confounded and two other extant texts: The Pearls (Al-La'ali' wa-l-durar) and The Casting Aside of the Clods for the Unstringing of the Pearls (Tarh al-madar li-hall al-la'ali' wa-l-durar).
