It’s Friday, time for fish. Above is a currently available reproduction of a pull-toy made by the incomparable Alexander Calder found here. Fridays and fish go together, I think, because both are very good for us and much too rare.

The tradition of eating fish on Friday developed in different places for different reasons. But in all sorts of places, fish boats normally spent all week at sea and brought their fresh catch home on Friday. So if you wanted the freshest fish, you bought and cooked the Friday fish.

Of course, in all parts of the world, there are fewer fish to be brought home. Which makes the ones we can get–and the ones we can’t–all the more valuable.

Above nice image (that’s a tiny piranha) here.

Artists of every era seem inspired by fish, including the biggest names of the 20th century.

Henri Matisse painted goldfish, 1911.

Picasso made a fish plate.

He also made a 3D ceramic fish thingy. Picasso even has a fish named for him

And another Alexander Calder, a fish mobile ( Fish, circa 1944). Hirshhorn Museum & Sculpture Garden.

But back to the actual creature that inspires all this. They are not just a feast for the stomach, but for the eyes of us land creatures. Look at fish and feel your eyes and nerves relax.

These tropical beauties live near Kenya.

Above is a lovely Aquarium in Lisbon, Portugal. You might stay all day.

More aquarium fish here at the Monterey Aquarium.

My town, Vancouver, has an aquarium too.

Jellyfish at Vancouver Aquarium. Nice photo from here.

Of course, it’s best to see sea creatures in motion.  It would be nice to spend time here (“Kuroshio Sea” aquarium, Okinawa, Japan)

Finally, remember, no matter what day of the week, it’s always time for FISH.
