We may associate graffiti with modern-day vandalism, but some daubings actually hold a great deal of significance. Take, for instance, the mysterious inscriptions that were discovered deep inside a cave in Alabama. While the individuals who wrote them are long gone, these cryptic messages endure – and now experts have finally begun to unravel their remarkable secrets.
Many ancient civilizations – among them the Romans and those once in Greece and Egypt – have left behind inscriptions. And these markings have often proved illuminating, too. On occasion, some etchings have helped us form better understandings of historic events such as the destruction of Pompeii; others, by contrast, have revealed fascinating details about ancient people and their ways of life.
