(Oxford, 1907), p. 259, “It was long before the mother could be distinguished from the daughter by any organic difference of form or by any expressive trait of countenance. On the more ancient vases and terracottas they appear rather as twin-sisters, almost as if the inarticulate artist were aware of their original identity of substance. And even among the monuments of the transitional period it is difficult to find any representation of the goddesses in characters at once clear and impressive. We miss this even in the beautiful vase of Hieron in the British Museum, where the divine pair are seen with Triptolemos: the style is delicate and stately, and there is a certain impression of inner tranquil life in the group, but without the aid of the inscriptions the mother would not be known from the daughter”; _id._, vol. iii. 274, “But it would be wrong to give the impression that the numismatic artists of this period were always careful to distinguish—in such a manner as the above works indicate—between mother and daughter. The old idea of their unity of substance still seemed to linger as an art-tradition: the very type we have just been examining appears on a fourth-century coin of Hermione, and must have been used here to designate Demeter Chthonia who was there the only form that the corn-goddess assumed. And even at Metapontum, where coin-engraving was long a great art, a youthful head crowned with corn, which in its own right and on account of its resemblance to the masterpiece of Euainetos could claim the name of Kore [Persephone], is actually inscribed ‘Damater.’ ” Compare J. Overbeck, _Griechische Kunstmythologie_, iii. (Leipsic, 1873-1878), p. 453. In regard, for example, to the famous Eleusinian bas-relief, one of the most beautiful monuments of ancient religious art, which seems to represent Demeter giving the corn-stalks to Triptolemus, while Persephone crowns his head, there has been much divergence of opinion among the learned as to which of the goddesses is Demeter and which Persephone. See J. Overbeck, _op. cit._ iii. 427 _sqq._; L. R. Farnell, _op. cit._ iii. 263 _sq._ On the close resemblance of the artistic types of Demeter and Persephone see further E.
