The Dutch style of 17th and 18th still life painting create a metaphor for morality is that all living wither away and die or birth and death. On the painting of Rachael Ruysch there so many things of both life and death as if the painter want to let the viewers see life has a beginning and an end.
Hector Rene Membreno-Canales uses the Dutch still life painting technique because he wanted this type of style to convey the experience in the military. Also to make the viewers see the truth on how war really is.
