Historians Figure Out How Ancient Sailors Navigated Mediterranean By Building One of Their Ships_我的网站

A |     What better way to figure out a mystery of the ancients than to try it out yourself? That’s what one sailing aficionado from Israel did when confronted with a puzzle from the Christian Bible.,David Gal, a doctoral student in the Department of Maritime Civilizations at the University of Haifa, says he has figured out why the Christian Apostle Paul sailed from Judea to Rome along the southern coast of Anatolia in 60 CE - a route that, to him, wasn’t the most obvious one, since most winds in the Mediterranean are westerlies and Paul was going west.,That year, Paul was sent to the imperial capital to answer to Jewish authorities for preaching the teachings of Jesus of Nazareth, who claimed to have been the Jewish messiah. Most Jews did not accept Jesus’ teachings, and he was tried and executed by crucifixion for blasphemy and subversion in either 30 or 33 CE.,Paul’s journey is recounted in unusual detail in the New Testament book of Acts. The preacher zigzagged his way across the sea, swinging north of Cyprus before heading to the city of Myra (modern Demre) in southern Anatolia. From there, he went west past Rhodes, to Knidos, then south to the southern coast of Crete and west across the southernmost parts of the Ionian Sea. However, he was shipwrecked in Malta and his journey took much longer than anticipated.,“Until recently, we didn’t understand why the Alexandrian grain ship that Paul joined in southern Anatolia, bound for Rome, chose that particular route,” Gal told Haaretz.,The boat, Ma’agan Mikhael II, is a replica of a ship found in 1985 about 2 meters underneath the seabed off the coast of Kibbutz Ma’agan Mikhael in northern Israel, not far from Caesarea. In ancient times, the city was known as Caesarea Maritima or Caesarea Palestine, named after the Roman emperor Augustus Caesar. The replica boat was finished in 2016 and is just one of two ships in the world that simulates a merchant sailing vessel from Before the Common Era (BCE).,By coincidence, Caesarea also happens to be the port from which Paul left on his trip to Rome.,In part, Gal’s study was based on computer modeling, which combined vast amounts of weather data and conducted 5,479 virtual sailing trips along 224 different possible routes from Caesarea to Rome, for a total of 1.2 million virtual sailing trips. However, that wasn’t enough: Gal also took a crew of 10 volunteer sailors out in the Ma’agan Mikhael II to explore the intangible human element of the journey. With just one sail, the ship moves along at a brisk 3.9 miles per hour.,“Only when we sailed on Ma’agan Mikhael II did we understand the real limitations of the ship and the sailors,” Gal told Haaretz. “We found that in many sections of the coast, the breeze doesn’t support this type of movement.”,“They didn’t sail counter to the prevailing wind, but waited for days with a favorable wind in the opposite direction,” Gal concluded. “We found there were such days in a large meteorological sampling. Until now, scholars didn’t examine that but used low-resolution meteorological averages that erase the variance in the wind.”,Gal said he has taken the ship out more than 80 times, sailing as far as Cyprus, and found that the daily wind patterns, in which breezes can blow westward from the Levantine coast, have remained strong after 3,000 years. By navigating those patterns, ancient sailors could have crept up the coast until they found more favorable winds.,“We have data about its performance in all wind conditions and how various currents affect it, and that enables us to conduct a reliable simulation of sailing. With its help, we acquired insights into the way such a ship is operated; we had a better understanding of how four people can sail from Greece to here and back,” he said.。    

[ 国内谍照] 日前,我们从相关渠道获得了一组腾势全新双门跑车的测试谍照,该车预计将会是在上海车展上发布腾势Z(参数|询价)概念车的量产版本。

B | 该车定位双门四座跑车,并有望搭载云辇-M和易三方系统。

腾势Z概念车
来看谍照,新车目前依旧处于测试早期阶段,不过下包围处的大尺寸扰流板以及前舱盖上的开口设计,我们都能够找到腾势Z概念车的影子。另外,上扬的车窗线条、隐藏式门把手以及两侧均配备充电接口等设计也与腾势Z概念车保持一致,因此预计量产版车型有望延续概念车的设计风格。
腾势Z概念车
腾势N7
内饰方面,我们能够看到其配备大尺寸液晶仪表和悬浮式中控屏设计,这与腾势Z概念车十分接近。不过测试车采用怀挡设计,方向盘造型与腾势N7较为接近,并且车门处也换装更为实用的设计风格,比概念车更加接近量产状态。此外,从谍照来看,新车虽然将会采用4座布局,不过后排空间十分有限,符合其跑车身份。
结合此前消息,腾势Z概念车将会配备易三方系统,最大功率400千瓦,可以实现0-100km/h加速3.2秒。另外车辆还将搭载线控转向、云辇-M和全线控底盘等等,操控部分值得期待。关于新车的更多信息,我们也将持续关注报道。
