roman painting is best known for what techniques?

Answer 1

While there is evidence that the Romans also painted on portable panels, the surviving paintings that we can see today were painted directly on the walls of their rooms, they used the following techniques: fresco; brightly colored backgrounds; division of the wall into multiple rectangular areas ("tic-tac-toe" design - where Roman painted walls are divided into three horizontal parts (dado, frieze, and cornice) and three vertical parts (left side, center, right side). multi-point perspective sometimes giving an Escher-like appearance; and trompe-l'oeil effects such as imitation of marble veneering.
