The book represents the comprehensive inquiry of both these aspects of arithmetic in his thought. The analysed sources are Gerbert’s so-called scientific letters written to his friends, colleagues or pupils, and also including some of his other texts. On this basis, attention is paid to arithmetic as the mother of all sciences and as the path to wisdom (e.g., the so-called \u003ci\u003eSaltus Gerberti\u003c\/i\u003e, relation between arithmetic and other disciplines of the quadrivium, etc.) and also to practical arithmetic (e.g., the introduction of Hindu-Arabic numerals and the re-introduction of a new form of abacus to the Latin Christian West).\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eTable of Contents\u003c\/b\u003e\u003cbr\u003e\u003cp\u003eArithmetic as the science of numbers\u003c\/p\u003e \u003cp\u003eTheoretical arithmetic:\u003c\/p\u003e \u003cul\u003e\n\u003cli\u003e\u003cp\u003e \u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003eThe Nature of Numbers: \u003ci\u003eSaltus Gerberti\u003c\/i\u003e (Letter to Constantine)\u003c\/li\u003e\n\u003cli\u003eFigurative Numbers and Geometry (Letter to Adelbold)\u003c\/li\u003e\n\u003cli\u003eMusic and Harmony (Two Letters to Constantine)\u003c\/li\u003e\n\u003cli\u003eAstronomy and Timekeeping (Letter \u003ci\u003eDe sphaera\u003c\/i\u003e, Richer’s \u003ci\u003eHistoria\u003c\/i\u003e,\u003ci\u003e \u003c\/i\u003eand the horological letter to Adam)\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003ePractical arithmetic:\u003c\/p\u003e \u003cul\u003e\n\u003cli\u003e\n\u003ci\u003e \u003c\/i\u003e\u003cp\u003e \u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ci\u003eTabula abaci\u003c\/i\u003e, decimal positional notation and\u003ci\u003e ghubar \u003c\/i\u003enumbers\u003c\/li\u003e\n\u003cli\u003e\u003ci\u003eRegulae multiplicationis\u003c\/i\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ci\u003eRegulae divisionis\u003c\/i\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Peter Lang AG","offers":[{"title":"Default Title","offer_id":51044532584791,"sku":"9783631858165","price":36.94,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0817\/1739\/5799\/files\/9783631858165.jpg?v=1750961929","url":"https:\/\/bookcurl.com\/products\/arithmetic-in-the-thought-of-gerbert-of-aurillac-9783631858165","provider":"Book Curl","version":"1.0","type":"link"}
