Ogham, Innisfallen, and Pratchett
Ogham is the Old Irish alphabet, usually seen carved into stones. The above example of Ogham, however, comes from MS. Rawl. B. 503, The Annals of Innisfallen.
This manuscript dates back to the 11th to 14th Centuries. The page excerpted here features an account of the building of the castle of Brí Uis and then gives a Latin inscription in Ogham letters:
Numus honoratur / sine numo nullus amatur.
This translates to Money is honoured/ without money nobody is loved, which is unfortunately not the most heartwarming of sentiments.
Speaking of which: Ogham formed the basis of Oggham, an ancient language in Terry Pratchett’s Lords and Ladies where it appears above an elven portal and spells out - and there’s no way to break this to you gently - “I’ve got a great big tonker.”
Ogham is one of the ancient scripts featured in the Taylor Institution Library’s current lecture series.
