This incident in Edgar's reign with some in Athelstan's, including the present to Harold Harfagra, King of Norway, of a very fine and rich chess table, and the account and description of seventy chessmen of different sizes, belonging to various sets, dug up in the parish of Uig, Isle of Lewis, are mentioned among the matters which cause the impression and assumption that a knowledge of chess had existed in the north of Europe, and in England earlier than the Conquest days assigned to it by all writers before Madden's views of 1832 appeared. So early as the Eighth century some courtesies began to be extended and enquiries made between contemporary monarchs on theological, scientific, and social matters. The presents received by the Carlovingian rulers from Constantinople and the East included the chess equipages deposited and preserved as sacred relics in France, which had belonged to Pepin and to Charlemagne. The latter was contemporary with the famous Harun Ar Rashid of Bagdad and Princess Irene and her successor Emperor Nicephorus of Constantinople. Greetings and embassies passed between them. Offa corresponded with Charlemagne and despatched the scholar Alcuin to assist him in refuting certain religious heresies (as alleged) propounded by one Felix, a bishop of Urgel. Egbert, we read, took refuge at Charlemagne's Court, was well received by him and served for a time in his army. Alcuin was the preceptor and became the life-long friend and adviser of Charlemagne, was domesticated with him and greatly revered in his family. 232 letters of Alcuin's are referred to in Forbes' edition. The Emperor's taste for chess, his celebrated chessmen and his communications on scientific and social matters with the East and elsewhere could be no secrets to Alcuin. Charlemagne seems to have fancied himself at chess, and from his avidity to find an opponent Alcuin may have been induced to test conclusions of chess skill with him. On his visit to England in 793 Alcuin brought his knowledge with him and he is the least unlikely person to have noticed chess and to have assisted in diffusing a knowledge of it in England.
