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.
洞穴壁画与我们的史前艺术家祖先们息息相关，但在美洲却一直缺少一个揭示此类远古艺术存在的证据。不过，如今科学家已在巴西发现了一个洞穴，那里面有迄今发现的世界上最古老的岩画。
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.
从2002年至2009年，科学家对这个很可能是远古人民用来遮风避雨的洞穴进行了发掘。最终，科学家们在那里找到了一个刻在基岩上的大约1英尺高的一个图像。它是一个人像，头部是C形，有两个张开的双臂和两条腿，还有一个非常明显的男性生殖器。
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.
借助放射性碳测年技术，研究人员认为该灰层的年龄在9300年和10,500年之间。在该图像上方一英寸的地方发现的一个壁炉也验证了科学家的这一推测。研究人员对沉积物使用了一种叫做释光定年的技术手段，结果也证明该图画可追溯到大约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.
科学家们称，这个岩石雕刻的发现可以证明，美洲存在着令人信服地最古老的石窟艺术。这项研究发表在《公共科学图书馆》杂志上。
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.
类似于这种风格的图画也存在于该地区的其它早期艺术中。它们款式多样，遍及北美和南美地区。研究人员称，这些图像的存在范围揭示了人类在该半球早期殖民统治的象征性思维。
