Portrait of Dom Miguel de Castro, Emissary of Congo is a 1643 painting by the Dutch Golden Age painter Jasper or Jeronimus Becx.

[1] The Dutch West India Company had conquered Loango-Angola in 1641 from the Portuguese, and they had heavily relied on the assistance of the Count of Sonho.

On 19 June 1643, Dom Miguel de Castro arrived in Flushing, where he was received by three directors of the Zealand chamber of the Dutch West India Company, and who provided him with accommodation in Middelburg.

[2] After John Maurice resigned his governorship of Brazil in early 1644, he visited Middelburg in October 1644 to settle his affairs with the Zealand chamber of the Dutch West India Company.

[6] The Senegalese photographer Omar Victor Diop made a self-portrait in reference to Dom Miguel de Castro' portrait for his 2015 exhibition Diaspora.
