Information: - Amphaxitis ( Ancient Greek : ) was called the western maritime part of the Mygdonia district of ancient Macedonia , on Axius river . - Polybius ("Polybios"; BC) was a Greek historian of the Hellenistic period noted for his work, which covered the period of 264146 BC in detail. The work describes the rise of the Roman Republic to the status of dominance in the ancient Mediterranean world and included his eyewitness account of the Sack of Carthage in 146 BC. Polybius is important for his analysis of the mixed constitution or the separation of powers in government, which was influential on Montesquieu's "The Spirit of the Laws" and the framers of the United States Constitution. - Thrace (Modern , "Thrake" "Trakiya") is a historical and geographic area in southeast Europe, centered on the modern borders of Bulgaria, Greece, and Turkey. In antiquity, it was also referred to as Europe, prior to the extension of the term to describe the whole continent. As a geographical concept, Thrace designates a region bounded by the Balkan Mountains on the north, Rhodope Mountains and the Aegean Sea on the south, and by the Black Sea and the Sea of Marmara on the east. The areas it comprises are southeastern Bulgaria (Northern Thrace), northeastern Greece (Western Thrace), and the European part of Turkey (Eastern Thrace). The biggest part of Thrace is part of present-day Bulgaria. In Turkey, it is also called Rumeli. The name comes from the Thracians, an ancient Indo-European people inhabiting Southeastern Europe. - Strabo ("Strabn"; 64 or 63 BC) was a Greek geographer, philosopher, and historian who lived in Asia Minor during the transitional period of the Roman Republic into the Roman Empire. - Mygdonia was an ancient territory, part of Ancient Thrace, later conquered by Macedon, which comprised the plains around Therma (Thessalonica) together with the valleys of Klisali and Besikia, including the area of the Axios river mouth and extending as far east as Lake Bolbe. To the north it was joined by Crestonia. The Echeidorus, which flowed into the Thermaic Gulf near the marshes of the Axios, had its sources in Crestonia. The pass of Aulon or Arethusa was probably the boundary of Mygdonia towards Bisaltia. The maritime part of Mygdonia formed a district called Amphaxitis, a distinction which first occurs in Polybius, who divides all the great plain at the head of the Thermaic gulf into Amphaxitis and Bottiaea, and which is found three centuries later in Ptolemy. The latter introduces Amphaxitis twice under the subdivisions of Macedonia (in one instance placing the mouths of the Echidorus and Axios in Amphaxitis, and mentioning Thessalonica as the only town in the district, which agrees with Polybius and with Strabo). In another place Ptolemy includes Stageira and Arethusa in Amphaxitis, which, if correct, would indicate that a portion of Amphaxitis, very distant from the Axios, was separated from the remainder by a part of Mygdonia; but since this is improbable, the word is perhaps an error of the text. - Bottiaea (Greek: "Bottiaia") was a geographical region of ancient Macedonia and an administrative district of the Macedonian Kingdom. It was previously inhabited by the Bottiaeans, a people of uncertain origin, later expelled by the Macedonians into Bottike (Chalcidice). In Roman times it was replaced by Emathia as a geographical term. - Therma or Therm was a Greek city founded by Eretrians or Corinthians in late 7th century BC in ancient Mygdonia (which was later incorporated into Macedon), situated at the northeastern extremity of a great gulf of the Aegean Sea, the Thermaic Gulf. The city was built amidst mosquito-infested swampland, and its name derives from the Greek "therm/therma", "(malarial) fever". Therma was later renamed Thessalonica by Cassander. By that time the port of the previous capital of Macedonia, Pella, had begun silting up, so Cassander took advantage of the deep-water port to the northwest of Therma to expand the settlement. - Claudius Ptolemy ("Klaudios Ptolemaios", ; ) was a Greek writer, known as a mathematician, astronomer, geographer, astrologer, and poet of a single epigram in the Greek Anthology. He lived in the city of Alexandria in the Roman province of Egypt, wrote in Koine Greek, and held Roman citizenship. Beyond that, few reliable details of his life are known. His birthplace has been given as Ptolemais Hermiou in the Thebaid in an uncorroborated statement by the 14th-century astronomer Theodore Meliteniotes. This is a very late attestation, however, and there is no other reason to suppose that he ever lived anywhere else than Alexandria, where he died around AD168.
