[10] Perkins represented the Puritan view of mnemonic techniques based on images, which considered them tainted with idolatry, heresy, Catholicism and obscenity.
[11] With Bruno and Dicsone, Perkins mentioned in his dedicatory epistle Metrodorus of Scepsis and Cosma Rosselli.
[13] It has been suggested that Dicsone was led to Bruno's memory theory by the requirement for memorable textbooks.
Hay was a Catholic and rebel, and Dicsone acted as a go-between for his master and the Scottish Kirk.
[16] Dicsone was in trouble with James VI of Scotland for carrying letters from Charles Neville, 6th Earl of Westmorland, an English Catholic in exile.
[18] Andrew Hunter wrote to Sir Robert Cecil in November 1598 that Dicsone was expected at The Hague and was an enemy to England.
[16] The secretary of Anne of Denmark, William Fowler sent news of Dicsone's death to Earl of Shrewsbury on 11 October 1603.
