Aristotle's work on fish species is one of the earliest known. In the 1500s fish enjoyed a renewed interest in both France and Italy. 1551 saw the appearance of Pierre Belon’s "Histoire naturelle des estranges poissons marins", illustrated by woodcuts. In 1554 Guillaume Rondelet’s "De piscibus marinis" was published, also using woodcuts. Salviani’s work was published in parts over a period of three years. Its use of copper engraving was well-suited to depicting fish, and greatly superior to woodcuts with its lifelike rendition of eyes and scales. The copper engravings have a scientific appearance, but some details, like the correct number and position of the scales were omitted. Nicolas Béatrizet probably designed the title-page and the fish illustrations were made by Antoine Lafréry. Another theory is that they were drawn by the Italian painter Bernardus Aretinus and engraved by Nicolas Béatrizet. Salviani's "Aquatilium animalium" only deals with animals personally observed and handled by him. He collected most of the fishes for his studies from the market in Rome.
Cum nimis absurdum was a papal bull issued by Pope Paul IV dated 14 July 1555. It takes its name from its first words: "Since it is absurd and utterly inconvenient that the Jews, who through their own fault were condemned by God to eternal slavery..."
With filming completed in Rome, production moved to Mexico City in late March to shoot the film's opening sequence, with scenes to include the Day of the Dead festival filmed in and around the Zócalo and the Centro Histórico district. The planned scenes required the city square to be closed for filming a sequence involving a fight aboard a Messerschmitt-Bölkow-Blohm Bo 105 helicopter flown by stunt pilot Chuck Aaron, which called for modifications to be made to several buildings to prevent damage. This particular scene in Mexico required 1,500 extras, 10 giant skeletons and 250,000 paper flowers. Reports in the Mexican media added that the film's second unit would move to Palenque in the state of Chiapas, to film aerial manoeuvres considered too dangerous to shoot in an urban area.
Mexico City is one of the most important economic hubs in Latin America. The city proper (Federal District) produces 15.8% of the country's gross domestic product. According to a study conducted by PwC, Mexico City had a GDP of $390 billion, ranking it as the eighth richest city in the world after the greater metropolitan areas of Tokyo, New York City, Los Angeles, Chicago, Paris, London and Osaka/Kobe (and the richest in the whole of Latin America). Excluding the rest of the Mexican economy, Mexico City alone would rank as the 30th largest economy in the world. Mexico City is the greatest contributor to the country's industrial GDP (15.8%) and also the greatest contributor to the country's GDP in the service sector (25.3%). Due to the limited non-urbanized space at the south—most of which is protected through environmental laws—the contribution of the Federal District in agriculture is the smallest of all federal entities in the country. Mexico City has one of the world's fastest-growing economies and its GDP is set to double by 2020.
