Who and when called the countries of Asia the countries of the East?

There are two points of view on this issue. However, they do not contradict each other.
1. Ancient Greece was at the origin of modern civilization. The countries of Asia were located to the east of it, therefore the Greeks called them “eastern”. Literary sources of that time have preserved this term and, through the millennia, it has come down to us.
2. The name could also appear in the era of the Great Geographical Discoveries, when the trade of Europeans with Asian states located to the east of Europe was actively developing.
Regardless of the origin, this name, in addition to geographical specifics, emphasized the opposition of two cultures: western and eastern.
For Europe in the Middle Ages and later, it also emphasized the religious opposition of Christianity and Islam.
