Unique Algebraic Remainders on the Sibṭ’s Commentary on the Yāsamīnīyya
This work is an elaboration of the commentary written by the Egyptian mathematician Sibṭ alMāridīnī—i.e., a commentary on another commentary—on the urjūzah (versified introduction) to the science of algebra, originally composed by the Berber mathematician and man of letters Abū Muḥammad ‘AbdAllāh alIshbīlī alMarrakushī, also known as Ibn alYāsamīn, who died in 1204 (600 AH). AlYāsamīn summarized his mathematical knowledge in a versified treatise known as the Yāsamīnīyya (The treatise by alYāsamīn). Around the end of the 15th century, alYāsamīn’s verses were the object of a ...


On the Sphere and the Cylinder; On the Measurement of the Circle; On Conoids and Spheroids; On Spirals; On the Equilibrium of Planes; On the Quadrature of the Parabola; The Sand Reckoner
In the middle of the 15th century, a number of manuscripts by the thirdcentury BC Greek mathematician Archimedes began to circulate in the humanistic centers in the courts of Italy. Piero della Francesca (circa 1416–92), the Renaissance artist best known for the frescos he painted for the Vatican and for the chapels in Arezzo, transcribed a copy of a Latin translation of Archimedes’s geometry (a compilation of seven surviving treatises) and illustrated it with more than 200 drawings representing the mathematical theorems in the texts. This manuscript, long ...


The Recension of Euclid's "Elements"
This work is a printed edition of Kitāb taḥrīr uṣūl liUqlīdus (The recension of Euclid's Elements) by one of the intellectual luminaries of the Islamic world, the Persian polymath Naṣīr alDīn Muḥammad ibn Muḥammad alṬūsī (1201–74). After his death alṬūsī was referred to as almuʿallim althālith (the third teacher, with Aristotle and Fārābī referred to as the first and second teachers, respectively). An extraordinarily prolific author, alṬūsī made notable contributions to most of the intellectual fields of his era, writing on theology, mysticism, logic ...


The Threefold Lily of Practical Arithmetic
Johannes Huswirth (Sanensis) was a German arithmetician who flourished around 1500. Nothing is known of his life. That he is sometimes referred to as Sanensis suggests that he may have come from Sayn, Germany. Arithmetice Lilium Triplicis Practice (The threefold lily of practical arithmetic) presents basic arithmetic operations such as addition and multiplication for whole numbers and fractions. It treats much of the same material that Huswirth had covered in an earlier work, Enchirdion Algorismi (Handbook of algorithms). The work includes two woodcut illustrations; one of God the Father and ...

He was expelled from Zhaoqing and went to Jiangxi, where in 1596 he became the superior of the mission. He lived ...

Bulgarian Arithmetic
Arithmetics were a popular genre of textbooks during the era of the Bulgarian National Revival in the 19th century, when it was widely believed that everyone, especially future businessmen, needed to know basic mathematics. Bulgarian Arithmetic was the fourth such text published in this era, in 1845. The author, Khristodul Kostovich SichanNikolov (1808–89), was a monk, teacher, writer, and publicist, often assisted in his scholarly pursuits by the writer, educator, and priest Neofit Rilski. Before writing his own text, SichanNikolov had been involved as the editor of the first ...
