In February 1617, Jan Lucasz. van Hasselt arrived in Persia accompanying Pietro Della Valle (1586–1652), a Roman noble. Sometime between 1618 and 1621 Van Hasselt entered the service of Shah ʿAbbas I (r. 1588–1629), for whom he worked as a painter until the death of the shah. Later, during the reign of Shah Safi I (r. 1629–42) and until 1654 he tried to establish himself as a commercial agent for Persia. The present paper examines the career of this Dutch painter in Persia and the Netherlands. Meanwhile the artworks that may be attributed to him will be discussed.
