The first Jesuit school in Ireland was established at Limerick by the Apostolic Visitor of the Holy See, David Wolfe. Wolfe had been sent to Ireland by Pope Pius IV with the concurrence of the third Jesuit General, Diego Laynez. He was charged with setting up grammar schools "as a remedy against the profound ignorance of the people". In 1565 preparations began for establishing a school at Limerick.
At his instigation, Richard Creagh, a priest of the Diocese of Limerick, was persuaded to accept the vacant Archdiocese of Armagh, and was consecrated at Rome in 1564. An English Jesuit, William Good, joined him. Good had completed the Spiritual Exercises in 1562 under the direction of Mercurian, and at his recommendation had been formally admitted to the Society of Jesus shortly before by Jean Montaigne at the Jesuit college in Tournai.
Wolfe intended to establish the first Irish Counter-Reformation school at Limerick, with the Primate's approval, and so it was intended that on arrival in Ireland Good should travel there, and be accompanied by a Limerick-born Jesuit scholastic, Edmund Daniel, who was a kinsman of Wolfe's. Ultimately, Good and Daniel would not enjoy a good relationship.
This early Limerick school operated in difficult circumstances. In April 1566 Good sent a detailed report to Rome of his activities via the Portuguese Jesuits. He informed the Jesuit General that he and Daniel had arrived at Limerick city two years beforehand and their situation there had been perilous. They established contact with Wolfe, but were only able to meet with him at night, as the English authorities were attempting to arrest the Legate. Wolfe charged them initially with teaching to the boys of Limerick, with an emphasis on religious instruction, and Good translated the cathechism from Latin into English for this purpose. They remained in the city for eight months, before moving to Kilmallock in December 1565 under the protection of the Earl of Desmond, where they lived in more comfort than the primitive conditions they experienced in the city. However they were unable to support themselves at Kilmallock and three months later they returned to the city in Easter 1566, and strangely set up their house in accommodation owned by the Lord Deputy of Ireland, which was conveyed to them by certain influential friends.
They recommenced teaching at Castle Lane, and imparting the sacraments, though their activities were restricted by the arrival of Royal Commissioners.
The number of scholars in their care was very small. The school was conducted in one large aula, but the students were divided into distinct classes. The top class studied the first and second parts of Johannes Despauterius's Commentarli grammatici, and read a few letters of Cicero or the dialogues of Frusius (André des Freux, SJ). The second class committed Donatus' texts in Latin to memory and read dialogues as well as works by Ēvaldus Gallus. Students in the third class learned Donatus by heart, though translated into English rather than through Latin. Young boys in the fourth class were taught to read. Progress was slow because there were too few teachers to conduct classes simultaneously.
