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]
Heart (symbol) The combination of the heart shape and its use within the heart metaphor developed at the end of the Middle Ages, although the shape has been used in many ancient epigraphy monuments and texts. With possible early examples or direct predecessors in the 13th to 14th century, the familiar symbol of the heart representing love developed in the 15th century, and became popular in Europe during the 16th.[1] Before the 14th century, the heart shape was not associated with the meaning of the heart metaphor. The geometric shape itself is found in much earlier sources, but in such instances does not depict a heart, but typically foliage: in examples from antiquity fig leaves, and in medieval iconography and heraldry typically the leaves of ivy and of the water-lily.
