The first known metal astrolabe in Western Europe is the Destombes astrolabe made from brass in the eleventh century in Portugal. [27] [28] (p 140) Metal astrolabes avoided the warping that large wooden ones were prone to, allowing the construction of larger and therefore more accurate instruments. Metal astrolabes were heavier than wooden ...
[9] [11] The astrolabe was confirmed by laser scanning, which revealed a series of 18 gradations marking 5-degree intervals, and has been named the Sodré astrolabe. It has been proposed that the Sodré astrolabe is a transitional instrument between the classic planispheric astrolabe from which the first mariner's astrolabes made of brass were ...

It appears to have been employed by Muslim, Jewish, and Christian communities spanning ...
Jost Bürgi and Antonius Eisenhoit: Armillary sphere with astronomical clock, made in 1585 in Kassel, now at Nordiska Museet in Stockholm. An armillary sphere (variations are known as spherical astrolabe, armilla, or armil) is a model of objects in the sky (on the celestial sphere), consisting of a spherical framework of rings, centered on Earth or the Sun, that represent lines of celestial ...
The mariner's astrolabe also measured the altitude of celestial bodies; it was developed from the so-called planispheric astrolabe, an analogue computer to solve a set of astronomical problems. In contrast with the planispheric astrolabe the Mariner's astrolabe cannot perform calculations but only be used to obtain the height of a celestial ...
He is known for making one of the oldest surviving astrolabes, dated 927/928, [2] as well as of another partially preserved astrolabe that bears his signature, "Made by Nasṭūlus in the year 315" of hijra (925). [2] [3] Very little is known about Nasṭūlus.
