Post Hoc Ergo Propter Hoc

One of the first lettering pieces I ever did was the phrase “correlation does not imply causation”, a piece which has since been lost in moving house, and is probably tucked away in the pages of a notebook hastily thrown into a box with the word “misc.” on the side. This week I decided to revisit the idea that inspired the first piece. The phrase deals with a logical fallacy that leads people to think that because two things happen together that one causes the other. Similarly, it’s easy to think that because one thing happens after another, the first causes the second. This fallacy is called “post hoc ergo propter hoc”, or after this therefore because of this.

Post Hoc Ergo Propter Hoc

Enough of that though, let’s get down to business. The interesting element of this piece, for me, is the Romans. The Copperplate may look flashy and the flourishes fancy, but when it comes to execution of a perfect letter, nothing provides the challenge, the depth and the satisfaction that Roman capitals do. Recently, though my study of Romans, I’ve been examining something called entasis.

Entasis is best know for its applications in architecture, some of it (surprise, surprise) by the Romans. The meaning of the word is a slight curve applied to something that looks mainly straight. When it comes to architecture, it was used to combat a strange optical illusion: perfectly straight columns have a tendency to trick the eye into seeing a curve where there is none. A slight bulge added to the columns is said to do away with the phenomenon and give the impression of straightness. In terms of calligraphy, however, the entasis is applied to the negative space between the letters. That is to say that the upright parts of the Roman capital have a thinning in the centre and widen towards each end. The execution of this with a broad nib or brush when doing calligraphy is a delicate manoeuvre and the effect is meant to be subtle. As this piece is also part of my study of entasis, I also kept the letters as close to traditional as I could, with understated serifs, a long crossbar on the E than you would see in a lot of modern work, and an open P.

Over the past few days I’ve been toying with the idea of starting to include more Gothic/Blackletter styles in my lettering after some study of their forms in calligraphy. As with all forms, I’m sure there is much to learn to inform future lettering pieces, so be on the look out in the future!
