It has also been remarked that this tendency to speculation led the Irish to admire the work of Martianus Capella whose volume was a sealed book to the school of York; while in the three great monasteries of Luxeuil, St. Gall, and Bobbio numerous MSS. in the original Irish character (Scottice scripta) of Origen and other Greek Fathers remained to attest the more inquiring spirit in which the studies of their communities were pursued. Thanks to his Greek studies and his natural mental attitude the Irish Theologian became a better astronomer as well as a better dialectician.[414] MUSIC: Music constituted an important element in Irish culture both in pagan and in Christian times. Hectateus, the great geographer quoted by Diodorus, is the first who mentions the name Celt and he describes the Celts of Ireland as singing songs in praise of Apollo and playing melodiously on the harp (c. 500 B.C.).[415] Native Irish literature abounds in reference to music and musicians who were always spoken of in terms of the highest respect. Everywhere through these ancient records we find evidence that the Irish people both high and low were passionately fond of music. It entered into their daily lives and formed a part of their amusements and celebrations of every kind.[416] Zeuss in his _Grammatica Celtica_ (1853) was the first to give the key to the nature of the musical instruments used in ancient Ireland. The references to music given by Zeuss were taken from glosses dating from 650 A.D. to 900 A.D. and written by the Irish monks of St. Gall. O’Curry,[417] Joyce,[418] and Flood[419] have followed up the work of Zeuss, so we have now a fairly clear idea of the state of musical culture during the period under investigation. Flood gives the names of twelve different instruments in use and of nine professional names of the performers.[420] It is not without significance that the harp is the national symbol. There are references to the harp in Irish literature probably as early as the fifth century.[421] O’Curry was so impressed with the many evidences he found of a high degree of musical culture that he could not restrain his enthusiasm. He says: “If ever there was a people gifted with a musical soul and sensibility in a higher degree than another I would venture to assert that the Ancient Gaedhil of Ireland were that people.”[422]
