  This article is to survey an anonymous treatise entitled fi [TawziḥAshkal] al-Usṭurlab al-Kuriy. The author, according to himself, wasan astrolabe maker; therefore, his description of the spherical astrolabeis probably based on a sample made by him. On the basis of thecomparison of this astrolabe with two other extant sphericalastrolabes, and according to some evidences, authors of this articleconcluded that this treatise is written in late sixth and early seventhcentury. There are at least three reasons for this claim. Furthermore,this article examines some interesting points about the etymology ofastrolabe, its usage, etc. Manuscript profile

  Ibn Saffār(370-426 AH), was an Andalusian Muslim astronomer and mathematician who authored several works on astronomy and also constructed the oldest-Sundial of Andalusia called Balāta To determine the time of prayer in noon and possibly afternoon. Since the Qibla is one of the sacred symbols of Islam, which has been at the center of Muslim attention for the centuries, finding the Qibla was especially important for this Muslim scholar. The question is how and in what way the qibla and the distance between Andalusia and Mecca have been obtained in the most famous work of Ibn Saffār, the Kitāb al-‘amal bi-l-asṭurlāb and also what were the characteristics of his “Balata” sundial?  To study this subject, it is necessary to know the mathematical methods in finding the Qibla as well as the sundials.The authors of the present paper  focus on Kitāb al-‘amal bi-l-asṭurlāb and also Balata sundial discuss about Ibn Saffar's role in the Andalusian astronomy and finding Qibla direction and determination of noon time there and based on the newly found chapters of her treatise, it has been concluded that he set the Cordoba qibla in the southeast direction and at an angle of 30 degrees to the rising sun during the winter solstice. The influence of this Astronomer from his master, “Maslama al‐Majrīṭī” (398 AH) and his attention to Kharazim's zīj, which was influenced by Zīj al-Sindhind and as well as Ptolemy's Geography indicates his reliance on Iranian, Indian and Greek sciences.

  Abdurrahman Mushfeqi Bukharaei is one of the poets of the tenth century AH who was familiar with composing sonnets and odes and was proficient in satire. Although in his time, unlike the fifth, sixth and seventh centuries, when the use of concepts of various sciences and knowledge in poetry was common, knowledge such as astrolabe and astrology was no longer considered and the poetry was close to the general language of the people, but Mushfeqi used astrological concepts in his poems. In his poetry, we not only come across common astrological concepts and words among most poets such as astrology and fortune-telling and the names of the septet planets, but also the topics and words that specialize in astrological knowledge such as south node, predestination, conjunction, honor, the concept of seeing lucky and unlucky hours we also see during his verses.
