MARRAKECH — Talk about main character energy. With the high-beat pace of today’s world and with busy lives juggling careers, families and personal projects, modern women are more akin to Ancient Greece’s Hercules and his 12 labors than to the demure muses of classical art. This action-hero script is what inspired “Mythica,” the latest high jewelry collection unveiled Wednesday by Louis Vuitton in a sunset show at the Kasbah D’If, a luxury property near Marrakech set on the edge of the Moroccan desert. Models wearing designs by artistic director of women’s collections Nicolas Ghesquière took a turn in front of an audience that included clients from around the world and celebrities such as Léa Seydoux, Alicia Vikander, Phoebe Dynevor and Ana de Armas.
