What perspectival systems did jan van eyck use to give a sense of depth to this painting, and where did he use them?

Explanation: Jan Van Eyck supposedly made use of underdrawings to create the Arnolfini Portrait. Arnolfini's hat was supposedly drawn over several times before the paint-covered brush touched the panel. Other elements of the work, such as the oranges, the pearls of the necklace and the dog, have been painted without underdrawings.

ive noticed that too but is this a question

violins play the melody in this section of sergei prokofiev's peter and the wolf.

hope this !
