The master of flemalle painted one of the first paintings that includes a sense of perspective and space

This statement is true. Robert Campin, who is also identified as "Master of Flemalle," was the first great painter of early Flemish and Early Netherlandish paintings. He was a painter of late 14th century. He was the first painter who showed more realistic observation powers. Campin used to paint more rounded characters by modeling light and shades, which gave his painting more sense of perspective and space. 

Hope this helps! :)
