What are "columns in antis?"

In Antis Columns are 'in antis" when they stand between square piers call anta.

With this post I'm joining Fifi Flowers' Fashionable Friday because this idea has been fashionable for several thousand years!

"Columns in antis"
is an old design idea, really old. This is a Leila Ross Wilburn foursquare arts and crafts house in Decatur, Georgia built about 1915.

It's an absolutely distinctive look that's literally 1000's of years old.

The square brick columns are anta, basically posts on either side of a doorway. The smaller columns between the anta are said to be "columns in antis."

It's a mostly a decorative effect these days. It's a look rather than a structural requirement. With modern materials, like steel beams, we don't need the interior columns. But in the old days, say 500 B.C., when the walls were soft brick or adobe, you needed strong posts (anta) at the corners and at the ends of a wall to hold lentils over a doorway.

It makes sense to our eyes: strong posts at the edges and something holding up the middle. Without the columns our brains sense something wrong. Classical ideas are about our brain chemistry and genes as well as aesthetics, function and physics.

Now that we know the term, let's keep our eyes peeled for columns in antis. This classical design idea has been in fashion for more than 2500 years. It's got at least 2500 years to go.

Here is another Leila Ross Wilburn home. Very nice and very different.

It's an effect you are more likely to see indoors. So check the magazines too.

How about a new (2003) home in Morningside:

They added on but they kept the columns

A bit of Victorian?

This one is very interesting. The columns sit on tall, chunky plinths. It's a very grand craftsman facade.

This one is really old, the Temple of Apollo Epicurius at Bassai, constructed between 450 BCE and 400 BCE. It's among the most beautiful buildings in the world. The columns in antis are outlined in pink.

The columns are long gone but the columns in antis were certainly there. Image courtesy User:Bibi Saint-Pol at Wikipedia.

Update April 5, 2009
Columns aren't just for temples. You can use classical ideas and proportions in Art Deco Buildings. Here are colossal (spanning more than one story), fluted "pilasters in antis" in the 1929 Troy Peerless Building. It's looking good.
