'THE LETTERS I CAUSED TO BE CAST'-- ROBERT BOYLE'S IRISH-CHARACTER PRINTING TYPE.

The article focuses on Robert Boyle's significant but often overlooked role in the creation of an Irish-character printing typeface in the late 17th century. Motivated by the unfinished Irish Old Testament translation of Bishop William Bedell and the lack of suitable Irish typefaces, Boyle commissioned a new font modeled on the Irish Franciscan types from Louvain, with punches cut by Joseph Moxon in London between 1678 and 1680. This typeface was used for key Irish religious texts, including Bedell's Old Testament and the Book of Common Prayer, and represents the earliest known Irish type produced in England. The Boyle/Moxon punches and matrices later passed through various English foundries and are now preserved in the Type Archive in London, highlighting their historical and bibliographical importance for Irish printing heritage.
