What were the similarties between northern and italian renaissance/?

Some of the differences from both were that the Italian renaissance obviously took place in Italy, more non-religious. and they had paid attention to anatomy and to human detail (also known as humanism). and had painted on a wet plaster. They took upon the enjoyment of worldy goods also focusing on greek and rome's pillars, arches, domes, etc.

The Northern renaissance had taken place out side of Italy but it was still in Europe. painted in oil on wood, and they were more religious. In this time they mainly focused on color and detail instead of humanism. focused more on mathematics and sciences
