...what about the magical number seven? What about the seven wonders of the world, the seven seas, the seven deadly sins, the seven daughters of Atlas in the Pleiades, the seven ages of man, the seven levels of hell, the seven primary colors, the seven notes of the musical scale, and the seven days of the week? What about the seven-point rating scale, the seven categories for absolute judgment, the seven objects in the span of attention, and the seven digits in the span of immediate memory?Yeah, what is it with that? George A. Miller, in a classic paper from 1956 explores a bit of the cognitive science lying behind the numerology of the number seven.
Update: Globetrotting blogger PF (who is now living in Istanbul after a
lengthy stay in Siberia) says that the Bosch picture above reminded him
of The Wheel of Samsara
which illustrates the essense of Buddhist teachings. It enumerates the
six worlds of Buddhist cosmology, the worlds of gods, men, animals, Hungry ghosts, warring titans and Hell (which
comes in both hot and cold varieties). Not a seven in sight however.
The text in the linked article gives a good rundown of the Wheel but the images are unfortunately fairly poor
so he has also provided links to this exquisite gallery of Himalayan Art which has many high resolution, zoomable versions of the Wheel.
