Edmund Campion's detailed negotiations with the Grocers' Company, still extant in beautifully neat minutes, reveal a close triangular relationship between the city companies, Paul's Cross, and the university of Oxford. On 12 April, only seven days earlier, Campion would have been in Christ's Hospital itself, which was only three hundred feet from Smithfield, where Thomas Loseby, Henry Ramsey, Thomas Thyrtell, Margaret Hyde and Agnes Stanley were burned as a group; the noise, smell and smoke must all have enveloped the consciousness of the boys and their teachers. The participation of Christ's Hospital in the Spital sermons is a reminder that the sermon culture was itself a part of a larger culture of disputation that began with inter-school competitions. It was a culture that rapidly spread across the entire system of grammar schools in England, and indeed throughout Europe.
