Imagine That: Roman Litter (the garbage kind)

I am starting an occasional series titled Imagine That, in which I imagine how things would have been in the ancient Roman world. I welcome all serious contributors!

Imagine that you are walking down a street in ancient Rome. What kind of natural and man-made litter, garbage, etc. do you see in and along the road?

• mud and dirt (goes without saying but I said it anyway)
• puddles of water
• feces and urine from animals and humans
• small, dead animals: dogs, cats, rats, birds
• bones and other parts/entrails from food: fish, pigs, goats, sheep, chicken, duck, goose
• fruit skins and rinds, olive pits, vegetable skins and seeds, spoiled food
• broken pottery and sherds
• old clothes, rags, and shreds
• scraps of parchment, papyrus, vellum (probably not much of this)
• sticks (but should have been used as fuel for fire), parts from old brooms
• bits of block, brick, stone, terra cotta
• broken toys, dolls, small statues/lares
• rarely, cool stuff like coins, stylus, glass vial or bottle, knife
• what am I missing?
