Claim: Osias Beert(c. 1580 – 1623)  is unlikely to have studied under his father and was a cork merchant which shows that he did not have a high income as an artist.
Evidence: Osias Beert or Osias Beert the Elder (c. 1580 – 1623) was a Flemish painter active in Antwerp who played an important role in the early development of flower and "breakfast"-type still lifes as independent genres in Northern European art. Osias Beert the Younger is unlikely to have studied under his father since his father is believed to have died when the son was very young. Beert was not only a painter but also traded as a cork merchant. The fact that he had a second occupation suggests that he did not gain a high income from his artistic work.
