This year the Italians celebrate the fiftieth anniversary of the proclamation of Rome as capital of United Italy. Apt as usual to seize the appropriate idea, they decided to mark the occasion in Rome herself by an exhibition that should not merely display the growth of present Italian art and industries, or afford hospitality to the art of other nations, but should set forth besides in visible monuments the former glory of Rome, the wide range of empire uled by the Eternal City, which, again a capital, is again the centre of a strong national life. Thus arose that unique feature of Rome's 1911 Exhibition, the Mostra Archeologica in the baths of Diocletian. The scheme of this section, as originally unfolded by Professor Lanciani at a meeting of the British School of Rome in the spring of this year, was limited to the life of the Roman provinces, whose chief monuments, whether in situ or in museums, were to be represented by casts and models, drawings and photographs. This programme has been adhered to in the main, in spite of certain later additions and accretions.
