    4.2 billion from 4 dials would require ~256 positions per dial, which these don’t appear to have anywhere near that many markings.

    It looks to me like each of the four is actually two dials stacked atop one another. And eight 16-position dials is also 4.2 billion.

    cool craftsmanship on the locking mechanism. but are those exposed pins for the main door? if so, it becomes more of a show of piece, than an actual locking box.

      It’s kind of the reverse, the ‘al-Asturlabi’ is a description saying he makes astrolabes, I’ve found various sources with slight variations on his name, but ‘Muhammad ibn Hamid al-Asturlabi al-Isfahani’ seems to be generally accepted and roughly means “Muhammad, son of Hamid, maker of astrolabes, from Isfahani”. It’s a bit of a mouthful, but the astrolabe bit was grafted on after he started making them.

        From Isfahan, Isfahani is the term for someone from Isfahan

      If I saw a name like that for an astrolabe inventor in fiction I’d say the author was lazy
