The authenticity of the Boston example of Mona Lisa is still in dispute. So far no serious objection to it has been brought forward, and there are certain points in its favour, as the presence of the columns which are reproduced in Raphael's sketch, and the bold brushwork of the drapery where this can be distinguished. But there is another example of the work in existence, and this fact, with the natural hesitation in pronouncing definitely on so important a matter, will probably leave the authenticity of the picture undecided for a long time. Meanwhile the literature upon Mona Lisa is ever increasing, and some important facts have been recently brought out. Amongst these is an announcement by A. C. Coppier that the lady was not a Florentine, but a Neapolitan of the Gheradini family, and that she was married in 1495, when eighteen years of age.[a] She would therefore be twenty-seven years old in 1504 when the picture which Raphael sketched is supposed to have been painted. But the Mona Lisa in the Louvre was completed between 1515 and 1519; hence there is much to ascertain as to the history of the work. [a] _Les Arts_, No. 145, 1914. NOTE 57. PAGE 172 The various suggestions that have been made as to the meaning of Mona Lisa's smile, seem to have no other foundation than the fancies of mystic minds. The smile has been called dangerous, sinister, ambiguous, provocative, purposely enigmatic, significant of a loose woman, expressive of sublime motherhood, reminiscent of Eastern intrigue, and so on, the mildest criticism of this kind affirming that the smile will ever remain an enigma. It is of course impossible for any meaning to be put into a smile by the painter, other than that of pleasure. Psychological suggestions are possible with the poet or novelist, but not with the painter. If there be any enigma or mystery in a picture, then the art is bad, for the work is incomprehensible, but there is no problem to be solved in Mona Lisa's smile. It is not different from any other smile except in degree, and of course in the quality appertaining to the particular countenance. Lionardo, with his scientific turn of mind, was not likely to attempt the impossible by trying to mix psychology with paint. NOTE 58. PAGE 178 It is necessary to dissent from the conclusion of Lessing as to the representation of ugliness by the poet. He says in referring to Homer's portrayal of Thersites[a]:
