A complete silver-inlaid penbox by the same artist was sold in these rooms 10th October 1989, lot 520. There he signed himself with his full name 'Muhammad b. Hamid al-Asturlabi al-Isfahani'. Other works by the same maker include a casket with combination lock in the David Collection, Copenhagen, another similar in the Boston Museum of Art, and four astrolabes. Both his father and brother were also metalworkers. An astrolabe by his father survives, while his brother, who also used the nisbah al-Asturlabi, made a penbox now in the L. A. Meyer Museum, Jerusalem.
