Deodat del Monte, Deodat van der Mont or Deodatus Delmont[1] (baptized 24 September 1582, in Sint-Truiden – 24 November 1644, in Antwerp) was a Baroque painter, architect, engineer, astronomer, and art dealer who was part of the inner circle of Peter Paul Rubens.

His father moved to Antwerp in 1590 after he was forced to leave Sint-Truiden in the Prince-Bishopric of Liège due to accusations of money forgery.

This is evidenced by del Monte's witnessing in 1608 of a contract between Rubens and the Oratorians for the execution of an altarpiece for the San Filippo Neri church in Ferro, Italy.

[4] Immediately upon his return to Antwerp with Rubens in 1608, del Monte was registered as a 'wijnmeester' ('wine master') of the local Guild of St Luke.

Del Monte joined the next year the 'sodaliteit of bejaerde jongmans', a fraternity for bachelors established by the Jesuit order.

The early biographer Cornelis de Bie asserts in his Het Gulden Cabinet of 1662 that del Monte was in the service of Wolfgang Wilhelm, Count Palatine of Neuburg for some time.

Some historians place this period of service in the 1610s but this is unlikely since during this time there are ample records of del Monte's presence in Antwerp.

Cornelis de Bie alleged that the king's son Philip IV of Spain intervened on Del Monte's behalf with his brother Cardinal-Infante Ferdinand of Austria, who at the time was the governor of the Habsburg Netherlands, and his privileges were restored.

It possibly helps explain why he was so highly regarded in his time and why the early artist biographer Cornelis de Bie dedicated more space to del Monte than to Jacob Jordaens and Anthony van Dyck.
