thin rod or stick based on the hollow socket at its base. The jewel certainly dates from Alfred's reign. Although its function is unknown, it has been often suggested that the jewel was one of the æstels – pointers for reading – that Alfred ordered sent to every bishopric accompanying a copy of his translation of the Pastoral Care. Each æstel was worth the princely sum of 50 mancuses which fits in well with the quality workmanship and expensive materials of the Alfred jewel. Historian Richard Abels sees Alfred's educational and military reforms as complementary. Restoring religion and learning in Wessex, Abels contends, was to Alfred's mind as essential to the defence of his realm as the building of the burhs. As Alfred observed in the preface to his English translation of Gregory the Great's Pastoral Care, kings who fail to obey their divine duty to promote learning can expect earthly punishments to befall their people. The pursuit of wisdom, he assured his readers of the Boethius, was the surest path to power: "Study wisdom, then, and, when you have learned it, condemn it not, for I tell you that by its means you may without fail attain to power, yea, even though not desiring it". The portrayal of the West-Saxon resistance to the Vikings by Asser and the chronicler as a Christian holy war was more than mere rhetoric or propaganda. It reflected Alfred's own belief in a doctrine of divine rewards and punishments rooted in a vision of a hierarchical Christian world order in which God is the Lord to whom kings owe obedience and through whom they derive their authority over their followers. The need to persuade his nobles to undertake work for the 'common good' led Alfred and his court scholars to strengthen and deepen the conception of Christian kingship that he had inherited by building upon the legacy of earlier kings including Offa, clerical writers including Bede, and Alcuin and various participants in the Carolingian renaissance. This was not a cynical use of religion to manipulate his subjects into obedience but an intrinsic element in Alfred's worldview. He believed, as did other kings in ninth-century England and Francia, that God had entrusted him with the spiritual as well as physical welfare of his people. If the Christian faith fell into ruin in his kingdom, if the clergy were too ignorant to understand the Latin words
