Dantiscus informs Giese that the King [Sigismund I Jagiellon] has agreed for the date of the [Royal Prussian] Diet to be moved to St. Michael’s Day [September 29]. He asks Giese to notify the neighbouring members of the Council, and he himself will notify the Voivode of Marienburg (Malbork) [Georg von Baysen (Jerzy Bażyński)], the Castellan of Gdańsk (Danzig) [Achatius von Zehmen (Cema)], and the councils of Elbing (Elbląg) and Gdańsk. He has already written to the Duke [Albrecht I von Hohenzollern-Ansbach] about the changed date.

Dantiscus sends Giese a letter received from the Vice-Chancellor [Samuel Maciejowski], describing the latest events.

The King made a decision on the Elbing castellany before the suggestions of Dantiscus and the Council members reached him. As a result of the support of the one who refused to sign the joint letter [Mikołaj Działyński, Castellan of Kulm (Chełmno)], the office was given to a less desirable candidate [Jan Sokołowski]. Dantiscus predicts further unfavourable developments and is worried about the future form of the Prussian Council.

Dantiscus asks Giese to admonish Doctor Nicolaus Copernicus, whom he has long respected highly as a person and a scholar, to dismiss the concubine [Anna Schilling] and not allow himself to be deceived any longer by Alexander [Sculteti], whom Copernicus prefers over other canons [of Ermland]. Dantiscus wants Copernicus to think the admonition is Giese’s own initiative.
