This is the Tesse tree.
This Church art shows the relationship of Jesus with Jesse and other biblical names. This design shows a branched tree growing from a reclining figure of Jesse. The various branches have pictures of other Old and New Testament figures who were ancestors of Jesus. At the top of the tree there are figures of Mary and Jesus.
Jesse was the father of the great King David of the Old Testament. He is the first person mentioned in St. Matthew’s gospel outlining the genealogy of Jesus.
