  • ROMANIZATION and SOME CILICIAN CULTS by HUGH ELTON (BIAA)
    ROMANIZATION AND SOME CILICIAN CULTS By HUGH ELTON (BIAA) This paper focuses on two sites from central Cilicia in Anatolia, the Cory­ cian Cave and Kanhdivane, to make some comments about religion and Romanization. From the Corycian Cave, a pair of early third-century AD altars are dedicated to Zeus Korykios, described as Victorious (Epinikios), Triumphant (Tropaiuchos), and the Harvester (Epikarpios), and to Hermes Korykios, also Victorious, Triumphant, and the Harvester. The altars were erected for 'the fruitfulness and brotherly love of the Augusti', suggesting they come from the period before Geta's murder, i.e. between AD 209 and 212. 1 These altars are unremarkable and similar examples are common else­ where, so these altars can be interpreted as showing the homogenising effect of the Roman Empire. But behind these dedications, however, may lie a re­ ligious tradition stretching back to the second millennium BC. At the second site, Kanhdivane, a tomb in the west necropolis was accompanied by a fu­ nerary inscription erected by Marcus Ulpius Knos for himself and his family, probably in the second century AD. Marcus then added, 'but if anyone damages or opens [the tomb] let him pay to the treasury of Zeus 1000 [de­ narii] and to the Moon (Selene) and to the Sun (Helios) above 1000 [denarii] and let him be subject to the curses also of the Underground Gods (Kata­ chthoniai Theoi). ' 2 When he wanted to threaten retribution, Knos turned to a local group of gods. As at the Corycian Cave, Knos' actions may preserve traces of pre-Roman practices, though within a Roman framework.

  • Siegfried Found: Decoding the Nibelungen Period
    1 Gunnar Heinsohn (Gdańsk, February 2018) SIEGFRIED FOUND: DECODING THE NIBELUNGEN PERIOD CONTENTS I Was Emperor VICTORINUS the historical model for SIEGFRIED of the Nibelungen Saga? 2 II Siegfried the Dragon Slayer and the Dragon Legion of Victorinus 12 III Time of the Nibelungen. How many migration periods occurred in the 1st millennium? Who was Clovis, first King of France? 20 IV Results 34 V Bibliography 40 Acknowledgements 41 VICTORINUS (coin portrait) 2 I Was Emperor VICTORINUS the historical model for SIEGFRIED of the Nibelungen Saga? The mythical figure of Siegfried from Xanten (Colonia Ulpia Traiana), the greatest hero of the Germanic and Nordic sagas, is based on the real Gallic emperor Victorinus (meaning “the victorious”), whose name can be translated into Siegfried (Sigurd etc.), which means “victorious” in German and the Scandinavian languages. The reign of Victorinus is conventionally dated 269-271 AD. He is one of the leaders of the so-called Gallic Empire (Imperium Galliarum; 260-274 AD), mostly known from Historia Augusta (Thayer 2018), Epitome de Caesaribus of Aurelius Victor (Banchich 2009), and the Breviarum of Eutropius (Watson 1886). The capital city of this empire was Cologne, 80 km south of Xanten. Trier and Lyon were additional administrative centers. This sub-kingdom tried to defend the western part of the Roman Empire against invaders who were taking advantage of the so-called Crisis of the Third Century, which mysteriously lasted exactly 50 years (234 to 284 AD). Yet, the Gallic Empire also had separatist tendencies and sought to become independent from Rome. The bold claim of Victorinus = Siegfried was put forward, in 1841, by A.

It purports that the majority of Rome’s security challenges fulfill the criteria of insurgency, and that Rome’s responses demonstrate counterinsurgency proficiency. These assertions are proven by means of an extensive investigation of the grand strategic, military, and cultural aspects of the Roman state. Fourteen instances of likely insurgency are identified and examined, permitting the application of broad theoretical precepts

In a typical book of Chinese literary history in any language, little, if anything, is said about Wu and Shu. This article argues that the consider- ation of the literary production of Shu and Wu is crucial to a fuller picture of the cultural dynamics of the Three Kingdoms period. The three states competed with one another for the claim to political legitimacy and cultural supremacy, and Wu in particular was in a position to contend with Wei in its cultural undertakings, notably in the areas of history writing and ritual music.

  • The Crisis of the Third Century A.D
    THE CRISIS OF THE THIRD CENTURY A.D. Dr. G.M. ROGERS Introduction Late in A.D. 155 the Greek orator Publius Aelius Aristides from Had- rianoi in Northern Mysia praised Roman rule in the presence of the im- perial court at Rome. Indeed, the poets say that before the rule of Zeus everything was filled with faction, uproar, and disorder, but that when Zeus came to rule, everything was put in order and the Titans were banished to the deepest corners of the earth, driven there by him and the gods who aided him. So too, in view of the situation before you and under you, one would suppose that before your empire everything was in confusion, top- sy-turvy, and completely disorganized, but that when you took charge, the confusion and faction ceased and there entered in universal order and a glorious light in life and govemment and the laws came to the fore and the altars of the gods were believed in'. According to Aelius, Rome had firmly established the basis for civi- lised life-security, the rule of law, and, most importantly, providentia deo- rum, the providence of the gods. The gods looked out for the inhabitants of the Roman empire2. A golden age had arrived. Later Edward Gibbon pronounced his famous verdict on the era from A.D. 96-I80. If a man were called to fix the period in the history of the world dur- ing which the condition of the human race was most happy and prospe- rous, he would, without hesitation, name that which elapsed from the death of Domitian to the accession of Commodus.
