The little coterie of artists, too, was on the verge of dispersal in any case, by the loss of Rembrandt's closest tie with it, Jan Lievensz. He had sold a picture of a man reading by a turf fire to the Prince of Orange, who had presented it to the English Ambassador, and he in turn had passed it on to that king of picture lovers, Charles the First, who had been so well pleased with it that a pressing invitation to visit England had been sent to the painter, and accepted. Nor, probably, was it only the chance of obtaining more employment that attracted Rembrandt. The famous "Anatomy Lesson" bears the date 1632, and, even if the commission for it had not actually been offered during the preceding year, it may very well have been suggested in the course of conversation by the doctor who had added to his name, Clæs Pietersz, that of Tulp, taking it from a tulip which was carved on the front of his house, who figures so conspicuously in it. If this were so, it must have been evident to Rembrandt that to undertake so large and important a picture while living in another city would mean either risking the uniformity and continuity of his work, or settling down for a prolonged period in lodgings in Amsterdam, and this may well have confirmed his decision to at once establish himself there permanently.
Finally, I like to fancy, though it certainly cannot be proved, that Rembrandt had already, in one of his flying visits to that city, met the girl upon whom, while she lived, the larger part of his life's happiness was to depend. The evidence is, it must be owned, slight, but is not altogether wanting. Among the pictures of the year 1630, and, according to M. Michel, even of 1628 and onwards, we find a series of portraits of a fair-haired girl with a round, full forehead, and rather small eyes and mouth, which Dr Bode believes to be portraits of the painter's sister Lysbeth, while M. Michel considers that some of the later ones are really portraits of Saskia, urging the objection that many of them were undoubtedly painted after his removal to Amsterdam, whither there is not the slightest reason to suppose that Lysbeth accompanied him, what evidence there is pointing directly to the contrary. On the other hand, M. Michel admits that the type which is known to be Saskia blends almost indistinguishably with that supposed to be Lysbeth, and offers the distinctly dubious explanation that Rembrandt was, so to speak, so imbued with the features of his sister that he unconsciously transferred them to a large extent to the girl he loved. If, however, as we may quite reasonably suppose, Rembrandt had met and admired Saskia during his first stay in Amsterdam, and continued to do so during his after-visits, the occurrence of her features in his work would be what we ought to expect.
