Statement
Bartlett’s Chi ratio is a term coined from Dirk Huylebrouck‘s presentation at Bridges Seoul of my discovery of this unique proportion which is related to the golden ratio. My meta-golden Chi rectangle has an aspect ratio of 1+√(4phi+5))/(2phi) = 1: 1.355… While a golden ratio rectangle can be divided into a golden ratio rectangle and a square, the Chi rectangle is new discovery in that it can be divided into a golden ratio rectangle and another Chi rectangle. My paintings follow that successive division for the dominant horizontals and verticals in the composition.This geometrical underpinning provides the necessary coherence of the visual design through repetition of varied but visually unified areas.
