We have many fine works of the fourth century of unknown authorship. Foremost of all--surely one of the six greatest statues in the world[90]--is the Demeter of Cnidos, in the British Museum, a statue so instinct with the spirit of Greek tragedy that but for certain technical points it ought to belong to the fifth century.[91] This is Mother Earth, Our Lady of Sorrows, mourning with sad eyes, but not in despair, for her daughter Persephone. The influence of Praxiteles may be traced in her brow and lips. The workmanship of this statue, as being, with the exception of temple reliefs, the finest Greek original in our Museum, deserves careful study. Very beautiful also is that sculptured drum from one of the thirty-six columns of the great temple of “Diana of the Ephesians,” another of the treasures of our Museum.[92] It is scarcely probable that time should have spared the one column which Scopas himself designed, but we may trace some of his influence in the emotional character of the faces, and much of Praxiteles in the grace of the attitudes and the poetry of the concept. The application of relief to a rounded surface is in itself a work of great difficulty, and we have seen how boldly it had been attempted in the same temple by artists of a much earlier day. This is a funeral scene such as might be represented on an Attic tombstone. In the centre is a matronly figure, headless, alas! fastening her mantle on her shoulder preparatory to the journey; on her left is Hermes, very young and boyish, extending his caduceus as if pointing downwards, but looking upwards to a point above the woman’s head. On her right is another figure, whom from his long wings and boyish form we should take, perhaps, for Love, were it not that his sad eyes and heavy sword mark him out as Death--a beautiful conception found also on the new Ludovisi relief and on some of the Athenian lecythi. Some think that the woman is Alcestis, and it is scarcely likely that any but a heroine, at the least, would occupy such a place in such a building. To make both these emissaries of death so young and charming is an idea typical of the fourth century, and especially of Praxiteles.
