Le Corbusier
Piet Mondrian
Salvidor Dali
Unbelievably tired, I’ve made every effort to tie up loose
ends, i.e., things yet unfinished and jobs requiring attention – the exception
being the completion of the patio on account of persistent light rain.
Some of these jobs were small, others required more time.
The most important task was preparing the Church Friends on Friday activity for
the 24th July. This will be an afternoon when attendees will be
offered an opportunity of doing pictorial art. I know there are ten more days before the
meeting, but a surprising amount of detailed preparation has to be done on my
part. This morning I was able to deal with the bulk of it, planning the content
and nature of the activities, plus buying paper, plastic rulers and setsquares.
Now, why would I want rulers and setsquares? Let me explain:
The art activity will be centred on the theme of the Golden
Section; also called the Golden
Mean, the Divine Section, the Golden Cut or the Divine Proportion. Basically, it is a naturally occurring mathematical
ratio of division found in nature. Some artists, designers and architects have
incorporated the ratio into their creative works. Notable examples can be found
in the works of the French architect Le Corbusier, the Dutch neoplastic painter
Piet Mondrian and the Spanish surrealist artist Salvidor Dali.

With regard to the Golden Section; imagine a horizontal
rectangle composed of a square and a vertical rectangle. The division between
them is represented by a vertical line. In the case of the Golden Section, the
ratio of division is 1 for the upper and lower sides of the square, and 0.618
for the upper and lower sides of the rectangle, giving a total of 1.618.
Roughly this is a division of 8 units for the sides of the square
and 5 units for the upper and lower sides of the rectangle. Divide 8 by 5 and
you will come up with the exact ratio of 1.6.
An analysis of some of the works of Le Corbusier, Piet
Mondrian and Salvidor Dali reveals that they structured them on the Golden Section.
They used Golden Section divisions as frameworks for strengthening and imparting
beauty to their creations.
The theme of the art work at the forthcoming Friends on
Friday gathering will be the Golden Section, and for determining where to make
divisions in their paintings and drawings, participants will be given rulers
and setsquares.
