12th-century mathematicians

The 12th century was a significant period for the development of mathematics, particularly in Europe, as it marked the beginning of the Western Renaissance in science and learning. During this time, several mathematicians and scholars contributed to the field, often through the translation and dissemination of works from the Islamic Golden Age and ancient Greek texts. Some noteworthy figures and developments in 12th-century mathematics include: 1. **Gerard of Cremona**: An influential translator, Gerard of Cremona (c.
