how and when was knowledge of paper making established in christian europe
History of paper Clear evidence of a water-powered paper mill dates to 1282 in the Spanish Kingdom of Aragon.[57] A decree by the Christian king Peter III addresses the establishment of a royal "molendinum", a proper hydraulic mill, in the paper manufacturing centre of Xàtiva.[57] The crown innovation originates from the Muslim Mudéjar community in the Moorish quarter of Xàtiva, where paper mills were a Muslim Mudejar operated enterprise.[58] However, it appears to be resented by sections of the local Muslim papermakering community; the document guarantees them the right to continue the way of traditional papermaking by beating the pulp manually and grants them the right to be exempted from work in the new mill.[57] Paper making centers began to multiply in the late 13th century in Italy, reducing the price of paper to one sixth of parchment and then falling further; paper making centers reached Germany a century later.[59]
