A heart
< span style="font-size: large">The ivy leaf, simplified, symbolized eternal love in Greek, Roman and early Christian cultures (ivy is a very long-lived plant). In the love literature of the 12th and 13th centuries ivy leaves appear in love scenes, soon painted in red, which itself is the symbolic color of love.
Too the heart symbol symbolizes the organ of the same name. Just as the organ is a metaphor for kindness and love, the heart symbol represents these same values.
