Back in Germany in 1164, he brought the bones of the Three Magi with him to Cologne as loot from Milan and as a gift of emperor Frederick Barbarossa; today they are still in the Cologne Cathedral. In the meantime the number of the adherents against the lawful pope increased in Germany. Rainald finally won the consent of the English king to common ecclesiastico-political action in behalf of Paschal III and once more took up arms in defence of his one ambition, which he hoped the proposed canonization of Charlemagne at Aachen in 1165 would advance. The new alliance was sealed by the engagement of King Henry's daughter Matilda with the Saxon duke Henry the Lion. In this period Rainald was notably the patron of the Archpoet.
