Perspective drawings by V. Pellegrin, 1873, and Ernest Norling, 1929

Fig. 1

Okay, I get it. Perspective is boring. Especially arcane drawings from some 19th century manual by the Professor of Topography at some Military School. True, the text (which you can read here) is as thick and dense as Dermot Malone who beat me up when I was a kid, but the drawings are amazing. Take the first one (Fig. 1), for example.

It shows how to draw a square in perspective (lmno), a column in perspective (m1, n1, q1, p1), and how to draw shadows cast in perspective (v2, u2, p2) ... all in one tiny little drawing. Note that the shadows also recede. Not only do they stretch back towards the horizon, but they have their own distance point at F1, which is a theoretical point that would be way under the ground somewhere. You know where to place the shadows by marking the intersection points between lines going back from the column towards the horizon, and lines cast by the sun (above and behind) that pass through the top corners of the column (p1, q1, u1, v1) and recede to F1. Simples.

Now you can delete this email and go about your day. See you in another couple of months with some more useless info. Bye!

I admit; some might be a tad complicated. But they still look cool.

Continuing from Figure 1, this shows an obelisk in perspective and how to construct appropriate shadows.

Maybe these next ones are a bit easier to follow. They're by Ernest Norling from Perspective Made Easy (1929). Maybe I should have posted these first, but they're not as cool-looking as Pellegrin's. And besides, nobody's made it this far into the post anyway.
