Greek sculpture existed in very early days, and we have vague accounts of a person called DAEDALUS, who seems to have been a wood-carver. Many cities claimed to have been his birthplace, and no one can give any clear account of this ancient artist. He is called the inventor of the axe, saw, gimlet, plummet-line, and a kind of fish-glue or isinglass. He is also said to have been the first sculptor who separated the arms from the bodies of his statues, or made the feet to step out; he also opened their eyes, and there is a legend that the statues of Daedalus were so full of life that they were chained lest they should run away. We call the time to which Daedalus belonged the prehistoric period, and his works and those of other artists of his day have all perished. Two very ancient specimens of sculpture remain--the Lion Gate of Mycenae and the Niobe of Mount Sipylus; but as their origin is not known, and they may not be the work of Greek artists, it is best for us to pass on to about 700 B.C., when the records of individual artists begin. Among the earliest of these was DIBUTADES, of whom Pliny said that he was the first who made likenesses in clay. This author also adds that Dibutades first mixed red earth with clay, and made the masks which were fastened to the end of the lowest hollow tiles on the roofs of temples. Pliny relates the following story of the making of the first portrait in bas-relief. Dibutades lived in Sicyon, and had a daughter called sometimes Kora, and again Callirhoe. She could not aid her father very much in his work as a sculptor, but she went each day to the flower-market and brought home flowers, which gave a very gay and cheerful air to her father's little shop. Kora was very beautiful, and many young Greeks visited her father for the sake of seeing the daughter. At length one of these youths asked Dibutades to take him as an apprentice; and when this request was granted the young man made one of the family of the sculptor. Their life was one of simple content. The young man could play upon the reed, and his education fitted him to be the instructor of Kora. After a time, for some reason that Pliny does not mention, it was best for the youth to go away from the artist's home, and he then asked Kora if she would be his wife. She consented, and vows of betrothal were exchanged, while they were sad at the thought of parting. The last evening of his stay, as they sat together, Kora seized a coal from the brazier, and traced upon the wall the outline of the face that was so dear to her; and she did this so correctly that when her father saw it he knew instantly from what face it had been drawn. Then he wished to do his part, for he also loved the young man. So he brought his clay and filled in the outline which Kora had drawn, and so went on to model the first portrait in bas-relief that was ever made. Thus did this great art grow out of the love of this beautiful maiden of Sicyon, about twenty-five hundred years ago.
