More than fifty of these Lives of Saints are known, composed generally in octosyllabic verse, and varying in length from some hundreds of lines to ten thousand. In the group which treats of the national saints of France, an element of history obscured by errors, extravagances, and anachronisms may be found. The purely legendary matter occupies a larger space in those derived from the East, in which the religious ideal is that of the hermit life. The celebrated _Barlaam et Joasaph_, in which Joasaph, son of a king of India, escaping from his father's restraints, fulfils his allotted life as a Christian ascetic, is traceable to a Buddhist source. The narratives of Celtic origin--such as those of the Purgatory of St. Patrick and the voyages of St. Brendan--are coloured by a tender mysticism, and sometimes charm us with a strangeness of adventure, in which a feeling for external nature, at least in its aspects of wonder, appears. The Celtic saints are not hermits of the desert, but travellers or pilgrims. Among the lives of contemporary saints, by far the most remarkable is that of our English Becket by Garnier de Pont-Sainte-Maxence. Garnier had himself known the archbishop; he obtained the testimony of witnesses in England; he visited the places associated with the events of Becket's life; his work has high value as an historical document; it possesses a personal accent, rare in such writings; a genuine dramatic vigour; and great skill and harmonious power in its stanzas of five rhyming lines.
