_The Principles of the Art of Conversation_: _A Social Essay_. By J. P. Mahaffy. (Macmillan and Co.) EARLY CHRISTIAN ART IN IRELAND (_Pall Mall Gazette_, December 17, 1887.) The want of a good series of popular handbooks on Irish art has long been felt, the works of Sir William Wilde, Petrie and others being somewhat too elaborate for the ordinary student; so we are glad to notice the appearance, under the auspicesof the Committee of Council on Education, of Miss Margaret Stokes’s useful little volume on the early Christian art of her country. There is, of course, nothing particularly original in Miss Stokes’s book, nor can she be said to be a very attractive or pleasing writer, but it is unfair to look for originality in primers, and the charm of the illustrations fully atones for the somewhat heavy and pedantic character of the style. This early Christian art of Ireland is full of interest to the artist, the archæologist and the historian. In its rudest forms, such as the little iron hand-bell, the plain stone chalice and the rough wooden staff, it brings us back to the simplicity of the primitive Christian Church, while to the period of its highest development we owe the great masterpieces of Celtic metal-work. The stone chalice is now replaced by the chalice of silver and gold; the iron bell has its jewel-studded shrine, and the rough staff its gorgeous casing; rich caskets and splendid bindings preserve the holy books of the Saints and, instead of the rudely carved symbol of the early missionaries, we have such beautiful works of art as the processional cross of Cong Abbey. Beautiful this cross certainly is with its delicate intricacy of ornamentation, its grace of proportion and its marvel of mere workmanship, nor is there any doubt about its history. From the inscriptions on it, which are corroborated by the annals of Innisfallen and the book of Clonmacnoise, we learn that it was made for King Turlough O’Connor by a native artist under the superintendence of Bishop O’Duffy, its primary object being to enshrine a portion of the true cross that was sent to the king in 1123. Brought to Cong some years afterwards, probably by the archbishop, who died there in 1150, it was concealed at the time of the Reformation, but at the beginning of the present century was still in the possession of the last abbot, and at his death it was purchased by Professor MacCullagh and presented by him to the museum of the Royal Irish Academy. This wonderful work is alone well worth a visit to Dublin, but not less lovely is the chalice of Ardagh, a two-handled silver cup, absolutely classical in its perfect purity of form, and decorated with gold and amber and crystal and with varieties of _cloisonné_ and _champlevé_ enamel. There is no mention of this cup, or of the so-called Tara brooch, in ancient Irish history. All that we know of them is that they were found accidentally, the former by a boy who was
