"I am not a type designer. This is the story of the creation of a new font, Avería: the average of all the fonts on my computer. The field of typography has long fascinated me, and I love playing with creative programming ideas, so it was perhaps inevitable that the idea came to me one day of “generative typography”. A Google on the subject brought up little, and I put the idea to the back of my mind until it occurred to me that perhaps the process of averaging, or interpolating, existing fonts might bring up interesting results. Luckily at this point I didn't do any more web searching – instead I grabbed my laptop and came up with an initial idea for finding what the average of all my fonts might look like – by overlaying each letter at low opacity. The results can be seen in the below image."

"So who was responsible and when is it from? Since the sheet is neither signed nor dated, we can only make this assertion thanks to the sleuthing done by earlier scholars, most importantly by John Dreyfus for his collection of type specimen facsimiles, and the source of much of the information I give here.1 This sheet can be connected to its type caster thanks to the detailed records kept by the Dutch printer Christophe Plantin and the remarkable longevity of his press, now the home of the Plantin-Moretus Museum. Plantin’s 1575 inventory of fonts includes the double pica italic typeface shown on this sheet (it’s the largest size of the italic face, on the right-hand column), with a note on the facing page identifying it as “Ascendonica Cursive de Guiot.” François Guyot was a type caster in Antwerp who worked from the 1540s until his death in 1570, and who was the main caster for Plantin from 1555 onwards; he also seems to have worked briefly for John Day in London."
