The first is the astronomical treatise now known as the Almagest, although it was originally entitled the Mathēmatikē Syntaxis or Mathematical Treatise, and later known as The Greatest Treatise. The second is the Geography, which is a thorough discussion on maps and the geographic knowledge of the Greco-Roman world. The third is the astrological treatise in which he attempted to adapt horoscopic astrology to the Aristotelian natural philosophy of his day. This is sometimes known as the Apotelesmatika (lit. “On the Effects”) but more commonly known as the Tetrábiblos, from the Koine Greek meaning “Four Books”, or by its Latin equivalent Quadripartite.
- Alexandria (Wikipedia)
Alexandria (/ˌælɪɡˈzændriə, -ˈzɑːn-/ AL-ig-ZA(H)N-dree-ə; Arabic: الإسكندرية; Greek: Ἀλεξάνδρεια, Coptic: Ⲣⲁⲕⲟϯ - Rakoti or ⲁⲗⲉⲝⲁⲛⲇⲣⲓⲁ) is the second largest city in Egypt and the largest city on the Mediterranean coast. It lies at the western edge of the Nile River delta. Founded in c. 331 BC by Alexander the Great, Alexandria grew rapidly and became a major centre of Hellenic civilisation, eventually replacing Memphis, in present-day Greater Cairo, as Egypt’s capital. Called the “Bride of the Mediterranean” internationally, Alexandria is a popular tourist destination and an important industrial centre due to its natural gas and oil pipelines from Suez.
