![]() ![]() ![]() As there is neither sun with us, nor any light of such a kind as to make shadows, we have none of the helps to the sight that you have in Spaceland. ![]() Well, that is just what we see when one of our triangular or other acquaintances comes towards us in Flatland. Figure 1 represents the Tradesman as you would see him while you were bending over him from above figures 2 and 3 represent the Tradesman, as you would see him if your eye were close to the level, or all but on the level of the table and if your eye were quite on the level of the table (and that is how we see him in Flatland) you would see nothing but a straight line. Take for example an equilateral Triangle - who represents with us a Tradesman of the respectable class. As soon as you look at it with your eye on the edge of the table, you will find that it ceases to appear to you as a figure, and that it becomes in appearance a straight line. ![]() The same thing would happen if you were to treat in the same way a Triangle, or a Square, or any other figure cut out from pasteboard. Place a penny on the middle of one of your tables in Space and leaning over it, look down upon it. ![]()
