Crepuscular rays are shafts of sunlight that stream through gaps in atmospheric clouds.
The shafts appear to radiate from a point in the sky, but are are nearly parallel. The convergence to a point in the sky observed on the ground, is actually a perspective effect analogous to how parallel train rails appear to converge at a distance.
“When you come right down to it all you have is yourself. The sun is a thousand rays in your belly. All the rest is nothing.”
― Pablo Picasso (1881-1973)
Crepuscular is derived from the Latin word crepusculum meaning twilight. Crepuscular rays frequently appear during the high contrast twilight hours of dawn or dusk.
“The human understanding is like a false mirror, which, receiving rays irregularly, distorts and discolors the nature of things by mingling its own nature with it”
― Francis Bacon (1561-1626)
