And that is why it is just as difficult to ascertain Rembrandt’s colouring as it is to discover accurately what greys were used by Velasquez. For the want of a better expression one might overcome the difficulty by speaking of Rembrandt’s gold; but it is very vague.

When I came to France I learnt to understand Delacroix and Zola perhaps better than many a Frenchman. And my admiration for both of these men is now as unbounded as it is sincere. Armed with an almost complete mastery of Rembrandt, I discovered that Delacroix obtained his effects by means of his colour, and Rembrandt by means of his values; but they are worthy of each other.

Zola and Balzac, who are, among other things, the painters of a whole epoch, afford their admirers many rare artistic delights owing to the fact that they express the whole of the age which they describe.

Even though Delacroix paints only mankind and life, instead of a whole age, he belongs none the less to the class of universal geniuses. I particularly like the closing words of an article which, if I am not mistaken, was written by Théophile Silvestre, who ended a hymn of praise as follows: “Thus, almost with a smile on his lips, did Eugène Delacroix die. A noble painter, he bore the sun in his head and a tempest in his heart, and he could turn from warriors to saints, from saints to lovers, from lovers to tigers, and from tigers to flowers.”

Daumier is also a great genius, while Millet is likewise the painter of a whole generation and of its atmosphere. Maybe, these great geniuses are a little crazy, and it is possible that we may be a little crazy too, to have such faith in them and to feel such unbounded admiration for their art. If this be so, I prefer my folly to the cold wisdom of others.

Perhaps the most direct way is to study Rembrandt. But, first of all, let me tell you something about Franz Hals, who has never painted the Saviour, the Angel announcing Christ’s birth to the shepherds, the Crucifixion or the Resurrection, and who has never painted naked, voluptuous, or cruel[{E}] female figures.

He always painted portraits and nothing else—soldier pictures, officers’ banquets, portraits of magistrates assembled to discuss affairs of State, and portraits of matrons with pink or sallow complexions, wearing white caps and dressed in black wool or satin, discussing the budget of an orphanage or a hospital.

He also painted a drunken toper, an old fishwife as a lively witch, a beautiful Bohemian courtesan, unweaned babies in arms, and an elegant[{F}] cavalier—a bon-vivant, with a bristly moustache, top-boots, and spurs.

He painted himself and his wife as young lovers, sitting on a grassy bank in the garden, after the wedding night.

He painted tramps and laughing street-boys, musicians, and a fat cook.
