Adolf visited Göteborg. In November 1624, the painter is rewarded with a golden chain with a miniature portrait of the king. He is recorded on 30 April 1624 in the Swedish court accounts as a portrait painter. He was in Altona (Hamburg) in 1626 where he married for the fifth and last time. Details about his last years are not available. His wife is recorded as a widow in Hamburg in 1633. Work Jacob Hoefnagel worked in various media and formats and is known for portraits, still lifes, mythological, scientific and topographical works, miniatures and emblems executed in oil, water colour, gouache and as engravings. Archetypa studiaque patris Georgii Hoefnagelii His first important work was the Archetypa studiaque patris Georgii Hoefnagelii, which he published in 1592 in Frankfurt. The book is a collection of 48 engravings of plants, insects and small animals shown ad vivum. It is divided in four parts of twelve plates (each with separate frontispiece), made after designs by his father Joris Hoefnagel and engraved by Jacob who was only 19 years old at the time of publication. The Italian scholar Filippo Buonanni asserted in 1691 that these engravings are the first published instance of the use of the microscope. However, this assertion of Buonanni is still contested. As the quality of the engravings varies, it is assumed that some of the works were made by members of the family De Bry who resided in Frankfurt. The prints in the collections were intended not solely as representations of the real world. They also carried a religious meaning as they encouraged the contemplation of god's plan of creation. Like contemporary emblem books each print carried a motto typically referring to god's interference in the world. The prints of the book were used as models by other artists and the Hoefnagel motifs were copied until the 19th century. It has been argued that the prints stood at the basis of the typical Dutch genre of still lifes with flowers, shells and insects. Painting Unlike his father who preferred drawing, Jacob was an accomplished oil painter who produced works in the Prague Mannerist style popularised by artists such as Hans von Aachen and Bartholomeus Spranger. As a painter Hoefnagel specialized in small format mythological or allegorical scenes on vellum or copper. During his stay at the court in Prague he produced many paintings of which only a few have survived.
