Light is the sole reason why life exists. It provides us with warmth; it allows us to see; it nourishes all the living things on this planet. Many painters, especially the masters of Old Renaissance Period, have recognized the importance of light and its intimate connection with nature and life itself. In their paintings they gave tribute to light, giving the impression that their paintings had a light source hidden within them. Al Hogue, the artist who created the paintings that you see before you, has studied their techniques for many years. As time went by, light permeated not only his paintings by also his life, becoming his sole philosophy.
