An apple of discord is a reference to the Golden Apple of Discord (Greek: μήλον της Έριδος) which, according to Greek mythology, the goddess Eris (Gr. Ερις, "Strife") said that she would give "to the fairest" at the wedding of Peleus and Thetis, sparking a vanity-fueled dispute between Hera, Athena and Aphrodite that eventually led to the Trojan War1. Thus, "apple of discord" became a euphemism for the core, kernel, or crux of an argument, or for a small matter that could lead to a bigger dispute. The Ancient Greek word "μῆλον" also means sheep or goat.[2]. Homer in his Odyssey describes how Odysseus sacrificed two goats (μήλα) when he reaches the underworld.[3]
