The Mediterranean lateen sailing rig has been studied since the early-to-mid-20th century. Recently-published depictions of sailing vessels rigged with lateen and settee sails, dating to the late-antique period, allow some of the principle characteristics of that rig to be established. This allows comparison with lateen- or settee-rigged vessels from both earlier and later periods. The sailing rigs depicted on other vessels can be identified and the level of technical continuity between the late-antique and medieval Mediterranean addressed. Finally it is possible to assess the extent to which the lateen sail was established in the Mediterranean by late antiquity.

Representations of ram‐like structures at the stern of warships mainly dating from the 5th century BC through to Late Antiquity suggest that ramming by the stern was an Illyrian tactic. When the Illyrian type of light warship, the liburnian, was introduced into Macedonian (?), Etruscan, and Roman navies, so apparently were rams. Coin images suggest a floruit in Late Roman fleets.  相似文献

The paper explores the use of ancient and historic material cultures and architectures within the recent resurgence in public commemoration in the UK. Using the case study of the National Memorial Arboretum (Staffordshire), the study focuses on how ancient designs (including prehistoric, classical and medieval styles and forms) interleave with the arboreal, geological and celestial themes of the memorial gardens. Together these designs serve to create a multitude of temporal poises by which auras of commemorative perpetuity and regeneration are projected and sustained. The paper proposes that archaeologists can bring their expertise to bear on the investigation of the complex, varied allusions to the past within contemporary landscapes of memory.  相似文献

Summary: The study of the feminine in ancient Iran is an area which deserves much greater attention than it has thus far received. By utilizing a number of primary sources, textual and otherwise, a few observations are offered here which concern the rites of women through the centuries. These evolving rites, which are described by the doctors of the then-dominant religion of Zarathustra, deal with the preservation of purity through seclusion of women in a world which is under constant attack from the demonic, polluting forces. Throughout the essay, the different means of fighting this battle are explored and suggestions for further research in the field are made.  相似文献
