Drawn up in 1775 by Dr James Butler, Archbishop of Cashel, and used in various editions and with some slight changes throughout Ireland for a century. A modified edition of Butler's Catechism was published in 1882 and became known as the "Maynooth Catechism." A new revision was undertaken by a committee of priests, in 1892, under the direction of William Walsh, Archbishop of Dublin, but the revised catechism was never published.
