Plato, Euthyphro 11d (trans. Lamb) (Greek philosopher C4th B.C.) :
"I am a more clever artist than Daidalos (Daedalus), inasmuch as he made only his own works move."
Plato, Meno 97d :
"Sokrates (Socrates) : You have not observed with attention the images of Daidalos (Daedalus). But perhaps there are none in your country.
Meno : What is the point of your remark?
Sokrates : That if they are not fastened up they play truant and run away; but, if fastened, they stay where they are . . . To possess one of his works which is let loose does not count for much in value; it will not stay with you any more than a runaway slave: but when fastened up it is worth a great deal, for his productions are very fine things."
[N.B. Sokrates pretends to believe the old legend that Daidalos crafted animate statues.
