4. There is Historical Graffiti Scratched onto the Temple of Dendur’s Walls
There are three different graffiti marks that were made on the temple walls over a period of a few thousand years, reports a New York Times article. The first, a few words scrawled in colloquial Egyptian script, dates to 10 BCE, just 5 years after the temple’s completion. Then in 400 CE, a few Greek Coptic Christian inscriptions were made while the temple was briefly converted into a Christian church.
The final graffiti marks that made it onto the temple’s walls came from 19th-century travelers who felt like chiseling their names into the sandstone. So somewhere on Dendur’s ancient walls, you can find a permanently etched “Leonardo 1820” (among other inscriptions).
