Synesius
Synesius (; el, Συνέσιος; c. 373 – c. 414), was a Greek bishop of Ptolemais in ancient Libya, a part of the Western Pentapolis of Cyrenaica after 410. He was born of wealthy parents at Balagrae (now Bayda, Libya) near Cyrene between 370 and 375. Life While still a youth (in 393), he went with his brother Euoptius to Alexandria, where he became an enthusiastic Neoplatonist and disciple of Hypatia. Between 395 and 399, he spent some time in Athens. In 398 he was chosen as an envoy to the imperial court in Constantinople by Cyrene and the whole Pentapolis. He went to the capital in occasion of the delivery of the ''aurum coronarium'' and his task was to obtain tax remissions for his country. In Constantinople he obtained the patronage of the powerful praetorian prefect Aurelianus. Synesius composed and addressed to Emperor Arcadius a speech entitled ''De regno'', full of topical advice as to the studies of a wise ruler, but also containing a bold statement th ...

Hypatia
Hypatia, Koine pronunciation (born 350–370; died 415 AD) was a neoplatonist philosopher, astronomer, and mathematician, who lived in Alexandria, Egypt, then part of the Eastern Roman Empire. She was a prominent thinker in Alexandria where she taught philosophy and astronomy. Although preceded by Pandrosion, another Alexandrine female mathematician, she is the first female mathematician whose life is reasonably well recorded. Hypatia was renowned in her own lifetime as a great teacher and a wise counselor. She wrote a commentary on Diophantus's thirteen-volume ''Arithmetica'', which may survive in part, having been interpolated into Diophantus's original text, and another commentary on Apollonius of Perga's treatise on conic sections, which has not survived. Many modern scholars also believe that Hypatia may have edited the surviving text of Ptolemy's ''Almagest'', based on the title of her father Theon's commentary on Book III of the ''Almagest''. Hypatia constructed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ptolemais, Cyrenaica
Ptolemais (Greek: Πτολεμαΐς) was one of the five cities that formed the Pentapolis of Cyrenaica, the others being Cyrene, Euesperides (later known as Berenice, now Benghazi), Tauchira/Teuchira (later Arsinoe, and now Tocra), and Apollonia (now Susa). Its ruins are at a small village in modern Libya called Tolmeita (''Arabic'' طلميتة), after the ancient name.Jane Soames Nickerson (Biblo & Tannen Publishers 1968 ), p. 20 History

Hydrometer
A hydrometer or lactometer is an instrument used for measuring density or relative density of liquids based on the concept of buoyancy. They are typically calibrated and graduated with one or more scales such as specific gravity. A hydrometer usually consists of a sealed hollow glass tube with a wider bottom portion for buoyancy, a ballast such as lead or mercury for stability, and a narrow stem with graduations for measuring. The liquid to test is poured into a tall container, often a graduated cylinder, and the hydrometer is gently lowered into the liquid until it floats freely. The point at which the surface of the liquid touches the stem of the hydrometer correlates to relative density. Hydrometers can contain any number of scales along the stem corresponding to properties correlating to the density. Hydrometers are calibrated for different uses, such as a lactometer for measuring the density (creaminess) of milk, a saccharometer for measuring the density of sugar in a liq ...

Cyrene, Libya
Cyrene ( ) or Kyrene ( ; grc, Κυρήνη, Kyrḗnē, arb, شحات, Shaḥāt), was an ancient Greek and later Roman city near present-day Shahhat, Libya. It was the oldest and most important of the five Greek cities, known as the pentapoleis, in the region. It gave eastern Libya the classical name ''Cyrenaica'' that it has retained to modern times. Located nearby is the ancient Necropolis of Cyrene. The traditional founder of the city was Battus the Lacedemonian, though the exact relationship between the fledgling city and other cities has led historians to question that narrative. Particularly, the idea that Thera was the sole "mother city" is disputed; and the relationship with other cities, such as Sparta and Samnium merchants, is unclear. Cyrene lies in a lush valley in the Jebel Akhdar uplands. The city was named after a spring, Kyre, which the Greeks consecrated to Apollo. It became the seat of the Cyrenaics, a famous school of philosophy in the fourth century ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aurelianus (consul 400)
Aurelianus (Greek: Αυρηλιανός, 393–416) was a prominent politician of the Eastern Roman Empire. He was ''praefectus urbi'' of Constantinople from 393 to 394, Praetorian prefect of the East from 399 to 400, and consul in 400. In 400, Gothic rebels under Gainas forced the emperor Arcadius to give them Aurelianus, and he was exiled; he returned to Constantinople after the defeat of the Goths later that year. He served as Pretorian Prefect to the East a second time from 414 to 416. Biography Aurelianus was the son of the consul of 361, Taurus, and brother of Caesarius; he had a son called Taurus, Consul in 428. Aurelianus was a Christian, and erected a church to protomartyr Stephen. Aurelianus was ''praefectus urbi'' of Constantinople between 393 and 394. When the Gothic ''magister militum'' Gainas rose to power at the court of Emperor Arcadius, he had all supporters of his enemy Eutropius removed; he chose Aurelianus as Praetorian prefect of the East (August 3 ...

Gainas
Gainas (Greek: Γαϊνάς) was a Gothic leader who served the Eastern Roman Empire as ''magister militum'' during the reigns of Theodosius I and Arcadius. Gainas began his military career as a common foot-soldier, but later commanded the barbarian contingent of Theodosius' army against the usurper Eugenius in 394. Under the command of Gainas, a man of "no lineage", was the young Alaric of the Balti dynasty. In 395, Stilicho sent him with his troops, under the cover of strengthening the armies of the East, to depose the prefect Rufinus, who was hostile to Stilicho. Gainas murdered Rufinus, but the eunuch Eutropius, who was likewise Stilicho's enemy, gained power. Gainas remained mostly unrewarded by the influential eunuch, which increased his resentment. In 399 he finally rose in stature by replacing ''magister militum'' Leo. This was after the latter failed to quell the insurrection of the Ostrogoths in Asia Minor, led by the chieftain Tribigild, who was also hostile ...

Pseudo-Democritus
Pseudo-Democritus is the name used by scholars for the anonymous authors of a number of Greek writings that were falsely attributed to the pre-Socratic philosopher Democritus ( 460–370 BC). Several of these writings, most notably the lost works ''On Sympathies and Antipathies'' and ''Artificial Substances'' (Greek: ), were probably written by the Pythagorean physician and pharmacologist Bolos of Mendes ( 3rd or 2d century BC). There are also a number of extant Greek alchemical writings attributed to Democritus, whose author has sometimes likewise been identified as Bolos of Mendes, but who is now thought to have been an anonymous author active during the second half of the first century AD, most likely c. 54–68 AD. These writings are some of the oldest alchemical works in existence, and have played an important role in defining alchemy as a discipline. In their original form, they probably consisted of a series of four books on dyeing: two ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dio Chrysostom
Dio Chrysostom (; el, Δίων Χρυσόστομος ''Dion Chrysostomos''), Dion of Prusa or Cocceianus Dio (c. 40 – c. 115 AD), was a Greek orator, writer, philosopher and historian of the Roman Empire in the 1st century AD. Eighty of his ''Discourses'' (or ''Orations''; ) are extant, as well as a few Letters and a mock essay "In Praise of Hair", as well as a few other fragments. His sobriquet ''Chrysostom'' comes from the Greek (), which literally means "golden-mouthed". Life He was born at Prusa (now Bursa), in the Roman province of Bithynia (now part of northwestern Turkey). His father, Pasicrates, seems to have bestowed great care on his son Dio's education. At first he lived in Prusa, where he held important offices, composed speeches and other rhetorical and sophistical essays, and studied philosophy. The Stoic and Platonist philosophies, however, appear to have had the greatest charms for him, particularly the stoicism of Musonius Rufus. He went to Rome during ...

Caesarius (consul 398)
Flavius Caesarius (''floruit'' 386–403) was a politician of the Eastern Roman Empire, who served under the emperors Theodosius I and Arcadius. Caesarius was ''magister officiorum'' (386-387), praetorian prefect of the East (395-397 and 400–403), and consul in 397. Biography Caesarius was the son of the Consul of 361, Taurus, and the elder brother of Aurelianus, with whom he contended for power. His devotion to his wife is noted by Sozomen. In 386 he is attested as ''magister officiorum''. As such, he was sent by Emperor Theodosius I to Antioch in 387, where the population had revolted against taxation. Caesarius, together with Ellobicus, then ''magister militum per Orientem'', held an inquiry. Caesarius paid particular attention for the situation of the citizens of Antioch and in his report to the Emperor pleaded for clemency for them. The Antiochian orator Libanius thanked him in an oration for this. Despite his merits, Caesarius was not appointed to higher offices in the fo ...

Goths
The Goths ( got, 𐌲𐌿𐍄𐌸𐌹𐌿𐌳𐌰, translit=''Gutþiuda''; la, Gothi, grc-gre, Γότθοι, Gótthoi) were a Germanic people who played a major role in the fall of the Western Roman Empire and the emergence of medieval Europe. In his book '' Getica'' (c. 551), the historian Jordanes writes that the Goths originated in southern Scandinavia, but the accuracy of this account is unclear. A people called the '' Gutones''possibly early Gothsare documented living near the lower Vistula River in the 1st century, where they are associated with the archaeological Wielbark culture. From the 2nd century, the Wielbark culture expanded southwards towards the Black Sea in what has been associated with Gothic migration, and by the late 3rd century it contributed to the formation of the Chernyakhov culture. By the 4th century at the latest, several Gothic groups were distinguishable, among whom the Thervingi and Greuthungi were the most powerful. During this time, W ...

Cyrenaica
Cyrenaica ( ) or Kyrenaika ( ar, برقة, Barqah, grc-koi, Κυρηναϊκή ��παρχίαKurēnaïkḗ parkhíā}, after the city of Cyrene), is the eastern region of Libya. Cyrenaica includes all of the eastern part of Libya between longitudes E16 and E25, including the Kufra District. The coastal region, also known as ''Pentapolis'' ("Five Cities") in antiquity, was part of the Roman province of Crete and Cyrenaica, later divided into ''Libya Pentapolis'' and ''Libya Sicca''. During the Islamic period, the area came to be known as ''Barqa'', after the city of Barca. Cyrenaica became an Italian colony in 1911. After the 1934 formation of Libya, the Cyrenaica province was designated as one of the three primary provinces of the country. During World War II, it fell under British military and civil administration from 1943 until 1951, and finally in the Kingdom of Libya from 1951 until 1963. The region that used to be Cyrenaica officially until 1963 has formed s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
