There are many legends and myths about pomegranates, which are filled with lots of red seeds. Illustrations that incorporate them or use them as a motif often do so for the symbolism, as the fruit is said to represent a plentiful harvest and life. In Greek mythology, they’re associated with the realm of the dead and, as such, can also have a dark nuance to their imagery. There are a lot of works on pixiv posted with this combination of life and death.
