Final answer:
The significance of Rembrandt's painting lies in its departure from traditional civic portraits and the depiction of the militia in action. Each figure, except the drummer, paid to be included in the painting.
Step-by-step explanation:
The significance of Rembrandt's painting, The Night Watch: The Militia Company of Captain Frans Banning Cocq, lies in its departure from traditional civic portrait compositions. Unlike other artists of his time, Rembrandt brought life and energy to the painting by depicting the militia heading out into the daylight rather than sitting statically around a table. Additionally, it is important to note that each of the figures in the painting, except the drummer, had paid to be included, highlighting the social importance and status associated with being part of such a militia.
