Conclusion. Thompson's conclusion is direct: The attribution of these manuscripts to Francis Tregian's hand is thus little more than an attractive legend. Never based on very solid biographical evidence, it is contradicted by the physical characteristics of the manuscripts themselves. Their paper strongly suggests that the manuscripts were prepared by a group of professional scribes working for patrons at court or connected to court circles. But a scriptorium capable of executing these commissions could scarcely have been brought into being expressly for that purpose. It is likely to have dealt with other, not necessarily musical, tasks, although no further manuscripts prepared by the same group have yet been identified.
