These conditions dictate that a cube must show the same sum in each horizontal, vertical, and front-to-back row, as well as in the four internal diagonals, to be considered magic.\u003c\/p\u003e\n\n\u003cp\u003eHowever, prior to this period, magic cubes were constructed following different rules. The earliest known study dates back to twelfth-century Persia. Pierre de Fermat (1601-1665) also investigated them during the seventeenth century. Unbeknownst to previous work and using a distinct design, the French mathematician Joseph Sauveur (1653-1716) introduced a construction method, which was later adopted by Gottfried Wilhelm Leibniz's (1646-1716) circle.\u003c\/p\u003e\n\n\u003cp\u003eThis method saw further development in the 1830s but eventually fell out of use once the modern definition of the magic cube took precedence.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Unknown","offers":[{"title":"Default Title","offer_id":47306901324012,"sku":"9782889156993","price":66.99,"currency_code":"NZD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0705\/7784\/8556\/files\/873aaede23737bada948ae29b760ef2c_2aca5f15-c20e-427c-a71a-1b88c7ceebd7.jpg?v=1771100464","url":"https:\/\/bookhero.co.nz\/products\/early-history-of-magic-cubes-11001850-by-jacques-sesiano-9782889156993","provider":"Book Hero","version":"1.0","type":"link"}
