Al-ʻIjliyyah was a skilled maker of astronomical instruments during the 10th century. She lived and worked in the city of Aleppo. This city is located in what is now northern Syria. She specialized in creating astrolabes, which are complex tools used for astronomy. These instruments allowed people to study the positions of stars and planets. Her work represents the scientific achievements of the Islamic Golden Age. Even with limited records, her legacy remains significant in science today.

To become an expert, Al-ʻIjliyyah had to undergo a specific training process. She and her father, also known as al-ʻIjliyy, were both apprentices. In this context, an apprentice is a student learning a specialized trade from a master. They studied under a maker named Nasṭūlus. This master lived in the city of Baghdad. Through this apprenticeship, they learned the precise skills needed to manufacture scientific tools. This training allowed them to eventually produce high-quality astrolabes for their community.

Al-ʻIjliyyah's professional life included working for high-ranking leaders. She was employed by the first Emir of Aleppo. This leader was named Sayf al-Dawla. He reigned over the city from the year 944 to 967. Having such an employer suggests that her instruments were highly valued. The production of these tools required great mathematical and technical precision. Her role as an astrolabist placed her at the center of medieval scientific life.

Historical records regarding her life are very specific but also quite limited. Most of what we know comes from a single writer named ibn al-Nadim. He is the only known source providing details about her life. In modern popular literature, she is sometimes called Mariam al-Asṭurlābiyya. However, the name "Mariam" does not appear in any historical sources from her era. The title "al-Asṭurlābiyya" is not a first name. Instead, it is a professional descriptor meaning "the astrolabist." This term simply identified her as a person who makes astrolabes.

Her influence extends far beyond the 10th century and into modern science. In 1990, an astronomer named Henry E. Holt discovered a main-belt asteroid. This is a large rocky object located in the space between Mars and Jupiter. To honor her memory, he named the object 7060 Al-ʻIjliya. The official citation for this name was published on 14 November 2016. This connection links her historical craftsmanship to the modern study of our solar system.

Al-ʻIjliyyah has also become a figure of inspiration in modern storytelling. Her life story has helped inspire characters in various creative works. For example, she inspired a character in the award-winning book titled Binti. She also inspired a character in the Netflix series Vikings: Valhalla. These depictions help keep the history of women in science alive for new audiences. She is recognized by the organization 1001 Inventions as an extraordinary woman from the Islamic Golden Age.

Her story connects to the broader history of astronomy and technology. The astrolabes she manufactured were vital for understanding the heavens. These tools were essential for navigation and timekeeping in the medieval world. By studying her life, we see how scientific knowledge was passed down through apprenticeships. We also see how women contributed to the technical fields of their time. Her name continues to be celebrated through both literature and the stars.
