where did the symbol of the poppy come from
Poppy Poppies have long been used as a symbol of sleep, peace, and death: Sleep because the opium extracted from them is a sedative, and death because of the common blood-red color of the red poppy in particular. In Greek and Roman myths, poppies were used as offerings to the dead.[5] Poppies used as emblems on tombstones symbolize eternal sleep. This symbolism was evoked in the children's novel The Wonderful Wizard of Oz, in which a magical poppy field threatened to make the protagonists sleep forever.[5]
Doves as symbols The use of a dove and olive branch as a symbol of peace originated with the early Christians, who portrayed the act of baptism accompanied by a dove holding an olive branch in its beak and also used the image on their sepulchres.[15][16]
