Through the acquaintances of his family, Niko meets Konstantino Parthenis in 1921 and, as he says, with him as his teacher, he "was introduced to art and entered from the big door". He had 10 lessons that opened his horizons on light and objects, geometric designs and colors. It is worthwhile for me to mention the words of Parthenis on this, he tells us. "For objects, there is no geometrically established pattern, because the form is altered in our eyes by the illumination ... An object acquires larger to us and on the canvas when light falls on it than that it actually is. Dimensions, therefore, change and diminish according to light. “Doesn’t this also happen to people in real life though?
