The Italian impact on European education dates back to the ancient Roman educators and scholars, outstanding among whom were Cicero, Quintilian, and Seneca. Later, during the Middle Ages, Italian universities became the model for those of other countries. During the Renaissance, Italy was the teacher of the liberal arts to virtually all Europe, particularly for Greek language and literature. The educational determine of Italy continued through the 17th century, when its universities and academies were Continental centers of teaching and research in the sciences. After a decline during the 18th and 19th centuries, Italian education regained international notice in the 20th century, partly as a result of the method for teaching young children developed by Maria Montessori.
