Cave painting connects us with our prehistoric artist ancestors. But there’s a dearth of such illustration in the Americas. Now a cave in Brazil has been found to house the oldest New World image known.
洞穴壁畫與我們的史前藝術家祖先們息息相關，但在美洲卻一直缺少一個揭示此類遠古藝術存在的證據。不過，如今科學家已在巴西發現了一個洞穴，那里面有迄今發現的世界上最古老的巖畫。
The shelter was excavated from 2002 to 2009. In the last days there, scientists exposed a foot-high figure in the bedrock. It has a c-shaped head, two outstretched arms, two legs, and a very visible penis.
從2002年至2009年，科學家對這個很可能是遠古人民用來遮風避雨的洞穴進行了發掘。最終，科學家們在那里找到了一個刻在基巖上的大約1英尺高的一個圖像。它是一個人像，頭部是C形，有兩個張開的雙臂和兩條腿，還有一個非常明顯的男性生殖器。
Using radiocarbon dating, the researchers dated an ash layer to between 9300 and 10,500 years ago. A hearth found about an inch above the drawing gives similar results. And the researchers used a technique called optically stimulated luminescence on sediment, which also dated to around 10-12,000 years ago.
借助放射性碳測年技術，研究人員認為該灰層的年齡在9300年和10,500年之間。在該圖像上方一英寸的地方發現的一個壁爐也驗證了科學家的這一推測。研究人員對沉積物使用了一種叫做釋光定年的技術手段，結果也證明該圖畫可追溯到大約10,000-12,000年前。
The scientists say this makes the petroglyph the oldest reliably dated cave art in the Americas. The research was published in journal Public Library of Science One.
科學家們稱，這個巖石雕刻的發現可以證明，美洲存在著令人信服地最古老的石窟藝術。這項研究發表在《公共科學圖書館》雜志上。
Echoes of this style exist in other early art in the region, amidst diverse styles throughout North and South America. The researchers the range of images reveals a spectrum of symbolic thought dating back to early in the history of human colonization of the hemisphere.
類似于這種風格的圖畫也存在于該地區的其它早期藝術中。它們款式多樣，遍及北美和南美地區。研究人員稱，這些圖像的存在范圍揭示了人類在該半球早期殖民統治的象征性思維。
