In august of 2017 there was a painting by lawren s. harris hanging at the mcmichael art gallery in kleinburg ont. he was a member of the group of seven. it depicts a triangle with 3 round lights at each angle. it was painted around 1920. the description of the painting refers to 'anti-gravity'. this would de-bunk the notion that today's triangular sightings are current technology that the government may be developing. the group of seven painted mostly (possibly all) their scenes from ontario canada sites.
