The ruins of the Roman Jerash next to modern-day city of Jerash
(picture credit to wikipedia)
"Jerash is known for the ruins of the Greco-Roman city of Gerasa, also referred to as Antioch on the Golden River. It is sometimes misleadingly referred to as the "Pompeii of the Middle East or Asia", referring to its size, extent of excavation and level of preservation (though Jerash was never buried by a volcano). Jerash is considered one of the most important and best preserved Roman cities in the Near East. It was a city of the Decapolis.
Jerash was the home of Nicomachus of Gerasa (Greek: Νικόμαχος) (c. 60 – c. 120) who is known for his works Introduction to Arithmetic (Arithmetike eisagoge), The Manual of Harmonics and The Theology of Numbers. In Boethius Latin translation, this book remained the standard mathematics textbook for the Latin European Middle Ages. "
