Who Was Isaac ibn Sid?

A writer named Isaac Israeli said that he saw notes written by Isaac ibn Sid himself. These notes described three times when Isaac watched and recorded moon eclipses. He did this because King Alfonso X asked him to. King Alfonso X of Castile even called Isaac "our learned Rabbi Çag" in official papers, showing how much he respected Isaac's knowledge.
In the year 1277, Isaac translated an important book from Arabic into another language. This book was all about a tool called a quadrant. A quadrant was an old tool used by astronomers to measure angles and positions of stars and planets. Isaac ibn Sid was also known for inventing other useful tools for studying the sky.
