Abstract We present an Arabic treatise on arithmetic, penned in Cherchell (Algeria) around 1575, of which five manuscripts are extant. The author, Ibrāhīm al-Balīshṭār, is a hitherto unknown Morisco mathematician from Aragon. After sketching his biography, we show that his treatise, claimed by him to be the translation of a book by a Christian priest, is actually an elaborate personal work, resulting from the intertwining of two Spanish treatises–those by Marco Aurel and Juan de Ortega–and of material drawn from Arabic authors such as al-Ghurbī, al-ʿUqbānī and Ibn al-Bannāʾ. It is therefore an original attempt to create a Euro-Islamic hybrid knowledge.

Ibrāhīm al-Balīshṭār 的算术书（约 1575 年）：西班牙数学论文与阿拉伯科学传统的混合

摘要 我们介绍了 1575 年左右在 Cherchell（阿尔及利亚）撰写的关于算术的阿拉伯论文，其中有五部手稿现存。作者 Ibrāhīm al-Balīshṭār 是一位来自阿拉贡的迄今不为人知的摩里斯科数学家。在勾勒出他的传记后，我们表明他的论文（他声称是一位基督教牧师的一本书的翻译）实际上是一部精心制作的个人作品，由两篇西班牙论文交织而成——马可·奥雷尔和胡安·德奥尔特加的那些论文——以及来自阿拉伯作家的材料，如 al-Ghurbī、al-ʿUqbānī 和 Ibn al-Bannaʾ。因此，这是创造欧洲-伊斯兰混合知识的原始尝试。
