What two ancient cultures influence the renaissance?

The two main cultures that influenced the renaissance were Ancient Greek and Ancient Rome.

Explanation:

The Christianity was emerged from the Ancient Rome culture so the scholars and philosophers who believed in Ancient roman culture were aware of the Greek culture as well.

The cultures followed the intellectual path and hence declined in middle ages. The renaissance is considered to begin from the Christianity teachings and the questions raised for the philosophers and scholars so it connects back to the Rome and Greek culture.
