Notes
20 x 15.5 cm The beginning of the manuscript: In the name of God, the Most Gracious, the Most Merciful, O conciliator, and I arranged it according to the introduction of forty-one chapters and the conclusion of the introduction to the naming of the drawings. I know that the astrolabe is an instrument by which many astronomical tasks are achieved in the easiest way and the closest to it is the relationship between the thread that is suspended... its moisture. I wrote the chapters, warning lines, and dividers in red ink, and the humidity affected the ink in some of the upper lines of the pages... The end of the manuscript: And when the planet sets, At night, add half an arc to the risings of its middle, and whatever it reaches is the risings of its setting, and if the risings of the planet’s setting are taken from the local risings or the past is cast from its arc, the remainder of it remains at its setting, even if the remainder is equal to the portion of dawn at the west of the beginning of the time of dawn, and God Almighty knows best of the worlds and is the wisest of judges, and praise be to God, Lord of the worlds.
