Astrolabe: dismounted reverse
Hajji 'Ali revived the Isfahan tradition of Safavid times by producing competent and aesthetically pleasing little astrolabes. His productions certainly figure among the best and most elegant astrolabes made in Iran after the mid-18th century, yet they are still much inferior to their Safavid archetypes. Hajji 'Ali is known to have manufactured at least 24 astrolabes.
The throne is ornamented with a floral design, which is typical of the astrolabes by this maker. In the mater is a gazetteer featuring 27 localities such as Baghdad, Qandahar and Astarabad. The shape of the rete closely follows the works of 'Abd al-A'imma, especially the retes on his smaller astrolabes. There are four plates for latitudes between 29â”œÃ²Ã”Ã²Ã˜-38â”œÃ²Ã”Ã²Ã˜. On the back of the instrument is a cartouche containing the maker's signature: 'Made by Hajji 'Ali / 128'. The only possible reading of the number is the year of construction: AH 128, which equates to 1793/94 AD. An inscription in the cartouche at the bottom informs us that this is the maker's 'thirteenth work'.
