So where does this leave the Dendera light bulb? There's no way every Roman household was crammed with batteries and light bulbs...but that's not to say this technology didn't have some important alternatives to household lighting - and that could at least explain the lack of physical evidence for an ancient light bulb in Roman cities. Think tunnels. During the Roman era more road and water tunnels were dug than at any time before the 1800s. Mining was booming and shafts were going ever deeper - and ever darker. Logically lighting these shafts was with oil lamps, but air quality would have been appalling - to the point where excavations may have become impossible. And, well, that would have cost money. The Dendera light bulb may have been a solution - and probably an expensive one. But was it? I don't know, maybe we should look more closely at Roman mines or tunnels for glass, copper rings and iron spikes. However, chances are, if these objects have been found, they have probably been described as...ritual objects.
