My own poor likeness, begun so long ago, still remains unfinished on the easel, at his departure from Valenciennes--perhaps for ever; since the old people departed this life in the hard winter of last year, at no distant time from each other. It is pleasanter to him to sketch and plan than to paint and finish; and he is often out of humour with himself because he cannot project into a picture the life and spirit of his first thought with the crayon. He would fain begin where that famous master Gerard Dow left off, and snatch, as it were with a single stroke, what in him was the result of infinite patience. It is the sign of this sort of promptitude that he values solely in the work of another. To my thinking there is a kind of greed or grasping in that humour; as if things were not to last very long, and one must snatch opportunity. And often he succeeds. The old Dutch painter cherished with a kind of piety his colours and pencils. Antony Watteau, on the contrary, will hardly make any preparations for his work at all, or even clean his palette, in the dead-set he makes at improvisation. 'Tis the contrast perhaps between the staid Dutch genius and the petulant, sparkling French temper of this new era, into which he has thrown himself. Alas! it is already apparent that the result also loses something of longevity, of durability--the colours fading or changing, from the first, somewhat rapidly, as Jean-Baptiste notes. 'Tis true, a mere trifle alters or produces the expression. But then, on the other hand, in pictures the whole effect of which lies in a kind of harmony, the treachery of a single colour must needs involve the failure of the whole to outlast the fleeting grace of those social conjunctions it is meant to perpetuate. This is what has happened, in part, to that portrait on the easel. Meantime, he has commanded Jean-Baptiste to finish it; and so it must be. October 1717.
