Where did you get that photo? I didn’t think they had cameras back then.
Wow, where have you been? Archaeologists discovered the hammer camera about a decade ago and now realize it was in widespread use for group pictures as early as 90 BC.
It was an hammer an chisel arrangement that you could stand in front of and as someone turned a crank it would rapidly chisel out a pattern of light and dark to recreate what was in front of it on whatever soft rock you put in place on the chisel tray. You could then take a piece of Goat gut, stretch it across the light and dark pattern, and with a roller you would transfer the pattern onto the goat gut. You then dried the goat gut and used it to make images from with any sort of pigment on the gut and fabric as the final media you would put over the gut and again run your little roller across the media to copy the pattern off of the goat gut.
Now the posted image has obviously been colorized and given the darkness of the image, it was probably made from the "instant" version of the camera that worked faster was called the hammeroid. The images weren't quite as good, but the hammeroid was portable so you could photograph things outside of a carefully prepared studio. Weddings, executions, and as we see above, feasts, were all popular subjects for those with hammeroids.
As I recall, someone made a goat gut image of Nero who then outlawed the hammerroid and destroyed all the earlier versions. Otherwise, we'd have a lot more pictures like the one above.
Try and keep up, OK?> /sarc from Wow to OK
