The familiarity of Georgian authors with the Persian classics also played a significant role in the development of Georgian literature. Monumental works such as the epic romance Amiran-Darejaniani ascribed to Mose Khoneli, Tamariani by Grigol Chakhrukhadze (12th century), Abdulmesiani by Iovane Shavteli and, finally, the masterpiece of Georgian poetry Vepkhistqaosani (The man in the panther skin) by Shota Rustaveli were written during this era of cultural synthesis.
