Melʹon
.Etre un melon. To be stupid or dull of comprehension. The melon-pumpkin or squash is soft and without heart, hence “être un melon” is to be as soft as a squash. So also “avoir un cœur de melon (or de citrouille)” means to have no heart at all. Tertullian says of Marcion, the heresiarch, “he has a pumpkin [pepʹonem] in the place of a heart [cordis loco].” It will be remembered that Thersiʹtēs, the railer, calls the Greeks “pumpkins” (pepʹonēs).
