I blame modern shoddy workmanship and refuse to correct their errors. Phidias in the 5th century BC was putting up buildings with the correct perspective when viewed from the ground. He curved the foundations so they looked correct when viewed. Of course he was building temples for the Gods. An example being the Parthenon in Athens.

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
