Apple of Discord
An apple of discord is the core, kernel, or crux of an argument, or a small matter that could lead to a bigger dispute. It is a reference to the Golden Apple of Discord () in the story "The Judgement of Paris" which, according to Greek mythology, was what the goddess Eris (Gr. Ἔρις, "Strife") tossed in the midst of the feast of the gods at the wedding of Peleus and Thetis as a prize of beauty, thus sparking a vanity-fueled dispute among Hera, Athena, and Aphrodite that eventually led to the Trojan War. Derivative uses. Because  of this, the Roman goddess corresponding to the Greek Eris was named "Discordia". Also, in German and in Dutch, the words are used a lot more often colloquially than in English, though in German the colloquial form is not "Apfel der Zwietracht" (lit. "Apple of Discord") but "Zankapfel" ("Quarrel-apple") and rarely "Erisapfel"; the Dutch is "twistappel" ("Strife-apple"). In the Eixample district of Barcelona, there is a block nicknamed in Spanish "La manzana de la discordia" (). The reason for this usage is that "manzana" means both "apple" and "city block" in Spanish. It was so named ("block of discord ) because it features four different interpretations of Modernisme" architecture: Antoni Gaudí's Casa Batlló, Lluís Domènech i Montaner's Casa Lleó Morera, Josep Puig i Cadafalch's Casa Amatller, and Enric Sagnier's Casa Mulleras. Section::::"To the Most Beautiful". In some later sources, Eris inscribed on the apple "for the fair" or "to the most beautiful" before tossing it. The most popular version of the inscription is ΤΗΙ ΚΑΛΛΙΣΤΗΙ (, Modern Greek: τη καλλίστη "ti kallisti"; "for/to the most beautiful"). "Καλλίστῃ" is the dative singular of the feminine superlative of καλός, beautiful. In Latin sources, the word is "formosissima". Apple
