An image of the Trinity fills the initial D that opens one of the eight major sections of psalms in the psalter. At the top of the scene and beneath an animal head, a dove representing the Holy Spirit descends towards two seated figures with crossed-nimbuses. Holding books and raising their hands in blessing, the two figures represent God the Father and Jesus Christ seated together on a bench. This presentation was inspired by the text from Psalm 109: Dixit d[omi]n[u]s domino meo: sede a dextris meis (The Lord said to my Lord: sit at my right hand).
