He remained at Leyden until 1631, moving then again to Amsterdam and beginning the greatest period of his life.

At Leyden he had painted much and etched much; perhaps the portrait of himself in a steel gorget, at The Hague, is his finest Leyden picture.

It was not until 1632, the year in which he married his Saskia, that the first of his most famous works, "The School of Anatomy," was painted.

Yet Leyden may consider that it was she that showed the way; she may well be proud.
Rembrandt's later life belongs to Amsterdam; but Leyden had other illustrious sons who were faithful to her to the end.

Chief of these was Jan Steen.
Harmens the miller, as we have seen, became the father of a boy named Rembrandt in 1606; it was twenty years later that Steen the brewer rejoiced over the birth of a son called Jan.
Of Jan's childhood we know nothing, but as a young man he was sent by his father to Utrecht to study under Nicholas Knupfer.
