Codex Balduini Trevirensis (also known as the Balduineum, or as Codex Balduineus), is an illustrated chronicle made c. 1340 for Baldwin of Luxemburg, archbishop of Trier and brother of the late emperor Henry VII.
It covers Henry's Italian campaign of 1310–1313, in which Baldwin himself had been a participant.
In this campaign, Henry sought papal coronation as emperor.
He entered Rome by force, but as St Peter's Basilica remained in the hands of his enemies he was crowned emperor at the Lateran[clarification needed] on 29 June 1312 by three cardinals of Pope Clement V (who was himself in exile at Avignon).
The codex consists of 37 parchment folia with large illustrations and short annotations describing the main events of Henry's campaign.
