Notes
21.4 x 14.5 cm. The beginning of the manuscript: Praise be to God, Lord of the Worlds, and prayers and peace be upon the best of His creation, Muhammad, his family, and all of his companions. I know that the first thing that is needed for the person looking at the astrolabe is to take the height. If you want to take the height, turn the astrolabe with its back, then hang it with your right hand and the left side of the sun, and make the ninety lines on the back of the astrolabe towards the eye of the sun. Its pages are tabulated in red ink within this group. The fifth message. Neither its title nor the name of its author was mentioned. I wrote the paragraph headers, the arithmetic numbers inside them, and the letters in red ink. It has traces of wetness. End of the manuscript: If you want to know the daylight shadow of your day, then reduce the arc of the halfday of your day from the risings between the risings, the cancer, to the end of the arc. So what is left, divide it by it, and whatever comes out is the shadow of the halfday of your day, and God knows best what is correct, and to Him is the return and the return.
