瑞士阿旺斯，9月29日——在经历有记录以来最炎热的夏季后，尘封已久的遗迹逐渐显现，考古学家据此重新描绘瑞士罗马时期的地图。
AVENCHES, Switzerland, Sept 29 - Archaeologists are redrawing Roman maps of Switzerland after traces of long-buried ruins emerged as the country endured the hottest summer on record.
干旱会使遗址上方的植被枯萎，从而显露出隐藏的考古遗址，并形成“地块痕迹”。这是今年热浪带来的多种影响之一；热浪还暴露了河床中的第二次世界大战时期残骸。
Drought can reveal hidden archaeological sites through "parch marks" created when vegetation above them withers, one of several effects of this year's heatwaves, which also exposed World War Two wrecks on river beds.
在一名历史爱好者提供线索后，瑞士沃州的考古学家使用无人机，每天拍摄阿文提库姆周边田地的影像。阿文提库姆是古罗马时期赫尔维提亚的都城，2000年前，尤利乌斯·凯撒击败当地部族后，这里开始建城。如今，阿旺斯小镇就坐落在这片遗址之上。
Alerted by a history enthusiast, archaeologists in the Swiss canton of Vaud used a drone to take daily images of fields around Aventicum, the former capital of Roman Helvetia, founded 2,000 years ago after Julius Caesar defeated local tribes. It is now the site of the small town of Avenches.
沃州考古学家乔丹·阿纳斯塔索夫说：“这是过去50年来当地最丰硕的一批发现，至少也是过去两代考古学家以来最丰硕的。”
"These are the richest discoveries made there in the last 50 years, at least over the last two generations of archaeologists," said Jordan Anastassov, archaeologist for Vaud.
影像显示出了此前未知或仅有初步认识的热水浴场、房屋、道路和一座可能存在的神庙等遗迹。其中许多位于这座城市的从未发掘过的区域。自3世纪起，随着日耳曼人入侵日益频繁，这座曾在罗马统治下繁荣的城市逐渐走向衰落。
The images revealed traces of thermal baths, houses, roads and a possible temple that were previously unknown or dimly understood, many in never-before-excavated areas of the city, which thrived under Roman rule before gradually fading as Germanic incursions increased from the third century onward.
由五名考古学家组成的团队用紫色将这些发现叠加到地图上，填补了地图空白，并纠正了错误标注。
The team of five archaeologists superimposed the discoveries onto maps in purple, filling blank spaces and correcting mistaken markings.
考古学家雨果·阿莫罗索说：“我们现在提出了一些非常有意思的问题，如果没有这些发现，我们根本不会想到要问这些问题。”
"We are now asking really interesting questions we wouldn't otherwise be asking," said archaeologist Hugo Amoroso.
6月至8月拍摄到的一些痕迹在割草和气温下降后消失了，但由于9月异常温暖的天气仍在持续，浴场中一处新水池的轮廓仍在一片部分枯萎的苜蓿田中显现出来。
Some of the traces captured from June to August vanished after mowing and with lower temperatures, but the perimeter of a new pool in the baths is still visible in a partially withered alfalfa field as unseasonably warm weather has persisted in September.
瑞士和欧洲其他地方也发现了其他埋藏的历史遗迹，但其中许多更难解读，因为这些遗迹较为孤立，且没有专门研究人员关注。
Other buried historical remains have emerged elsewhere in Switzerland and Europe, but many are harder to interpret because they are isolated and lack dedicated researchers.
瑞士考古学家将向同行展示这些发现，日后还可能开展有针对性的发掘。
The Swiss archaeologists will present their findings to peers and may conduct targeted digs later.
“我们不会盼着发生旱情，”该遗址发掘负责人皮埃尔·布兰说，“但我们会充分利用这一情况，继续寻找。” 路透社
"We aren't going to wish for droughts," said Pierre Blanc, director of excavations for the site. "But we're going to make the most of this and keep looking." REUTERS
