The traditional site of this church is indicated by Church Place as it is called to-day. The cloisters probably lay to the south of the church, round "Penson's Gardens." As the Franciscans fell away by degrees from the ideal of poverty, so also they succumbed to the desire of knowledge. "I am your breviary, I am your breviary," S. Francis had cried to a novice who had asked for a Psalter. The true Doctors, he held, were those who with the meekness of wisdom show forth good works for the edification of their neighbours. But the very popularity of their preaching drove his disciples to the study of theology. Their desire not only to obtain converts but also to gain a hold on the thought of the age had led the friars to fasten on the Universities. The same purpose soon led them to establish at Oxford a centre of learning and teaching. Their first school at Oxford was built by Agnellus of Pisa, and there he persuaded Robert Grossetete, the great reforming bishop of Lincoln, to lecture. Agnellus himself was a true follower of S. Francis and no great scholar. "He never smelt of an Academy or scarce tasted of humane learning." He was indeed much concerned at the results of Grossetete's lectures. For one day when he entered this school to see what progress his scholars were making in literature, he found them disputing eagerly and making enquiries whether there was a God. The scandalised Provincial cried out aloud in anger, "Hei mihi! Hei mihi! Fratres! Simplices coelos penetrant, et literati disputant utrum sit Deus!" The miracles which were afterwards reputed to be performed at the grave of this same excellent friar caused the church of the Grey Friars to be much frequented. The friars now began to accumulate books and we soon find mention of two libraries belonging to them. The nucleus of them was formed by the books and writings of Grossetete, which he bequeathed to the brethren. And they collected with great industry from abroad Greek, Hebrew and mathematical writings, at that time unknown in England. The fate of this priceless collection of books was enough to make Wood "burst out with grief." For, when the monasteries had begun to decay, and the monks had fallen into ways of sloth and ignorance and were become "no better than a gang of lazy, fat-headed friars," they began to sell their books for what they would fetch and allowed the remainder to rot in neglect.
