Do Typefaces Matter?

From bbc.co.uk/news/magazine

The BBC News Magazine has an article on the importance of typefaces. With thanks to a tip from the Typo-L listserv.

"To most people, typefaces are pretty insignificant. Yet to their devotees, they are the most important feature of text, giving subliminal messages that can either entice or revolt readers, says Tom de Castella.

When Avatar, the biggest grossing movie of all time was released, one section of the audience was immediately outraged . . ."

You Will Not Be Taken Seriously If You Use Comic Sans

Here is further proof. Really. For the sake of one's dignity, some fonts are best avoided.

Volvelles

Volvelles are paper wheel charts with rotating parts. The modern ones, such as those reproduced in Jessica Helfand's Reinventing the Wheel, are enjoyable. But there's something so captivating about the ones from previous centuries that were incorporated into books. These were used for serious stuff like astronomy, medicine and fortune-telling. They were computing devices in their day. To think that the modern movable book has such exalted ancestry.

When I posted a picture recently of a volvelle from Petrus Apianus's 1529 Cosmographia, it whetted my appetite for more. Here are a couple of other examples from the Cosmographia.

According to the Lambeth Palace Library Exhibition catalogue, Petrus Apianus (1495-1552) was a mathematician and a pioneer in astronomical and geographical instrumentation. The Cosmosgraphia was a European best-seller. It appeared over the next century in as many as 45 editions in 4 languages, printed in 7 cities by at least 18 printers. It contained four volvelles.

Here are a few links to historical volvelles:

Robert Sabuda has a brief history, with pictures. An early one, pictured below, was made by a Benedictine monk in 1250 and was used to determine when to observe holidays. Some say it is the earliest known example of a volvelle.

A few reproductions from the 1552 Astronomicon Caesareum, which contained 35 volvelles, can be found here. The following image from it is thanks to the Wikipedia page on Volvelles:

This page also has a brief history of volvelles and some more pictures from the Astronomicon C., among others, but be warned that several of the links here no longer work.

Doesn't it just make you want to start cutting and assembling circles?
