Jan Harmensz. Muller (1571–1628) was a Flemish engraver and painter.
His father was a book printer, engraver and publisher. He learned the engraving trade while working at the family business, and he was trained also by Hendrik Goltzius.
He traveled and lived in Italy for a time. Muller returned home, inherited his father’s business, and died in 1628.
His principal works are: Rape of Sabine; Couple embracing; Two studies of Atlas; Masked Ball; Head; Agar in the desert; The Prodigal son being seduced; and Raising of Lazarus’.
We know only 90 engravings by Müller, 20 of them after own drawings.
