Brightly-painted Zapotec murals invoking warfare recently unearthed from tombs in southern Mexico may date back nearly 2,000 years, officials said late on Wednesday of the find that sheds new light on the ancient civilization's funerary rites.
The well-preserved murals found in the largest of five tombs, its chambers arranged in a cross-like structure, show sharp black lines and richly-dressed figures painted in colorful red and yellow hues, in the town of San Pedro Nexicho, in southern Oaxaca state.
