Which painting by Rembrandt was refused after commission?

The painting by Rembrandt that was refused after commission is "The Night Watch" (1642). Originally titled "The Militia Company of Frans Banning Cocq," it was commissioned by the Amsterdam militia but faced criticism for its unconventional composition and portrayal of the subjects. The rejection stemmed from the expectations of the time for formal group portraits, which Rembrandt subverted through his dynamic use of light and movement. Despite the initial refusal, "The Night Watch" is now celebrated as one of his masterpieces.
