Quote:did they have undwear under those tunics?
Subglicanum (spelling?) in all materials, some rather scratchy. Going 'commando' was also very common.
Quote:did they use soap, if they used oil what kind?
There are byzantine mentions of recipes for soap. Very heavy on lye, which probably took the skin with the dirt. More common was sweating out the dirt and scraping with oil and strigil.
Quote:a sponge on a stick was there toilet paper?
Yep. Some brought their own stick, but there were also communal ones and little troughs of water to rinse them off. Remember, the germ theory of medicine is 1800 years away. A properly rinsed sponge looked clean...so...
Quote:how did roman heat there homes? wouldnt it be terribly cold in winter?
and bug infested in summer?
Wealthy homes had hypocausts, raised floors with furnaces to push hot air underneath, not terribly common though. The Aula Palatina in Trier supposedly had one though. Most homes used movable braziers or open fires.
Rome is a lot colder than you think and Tuscany and Umbria are downright miserable in winter. When St. Francis praised the snow and brother fire, he wasn't kidding. Last year was horrible. I got snowed on in Assisi last March.
Most homes have an impluvium or rain basin in the front part or atrium of the house. It was open to the sky. Open windows and the hot air passes over the impluvium and carries it upward. Evaporative cooling! Roman houses have almost no exterior windows to minimize heat. Still, there is only so much you can do and lots of Roman writers complain about bugs, cold, rotting food. You probably had to grow used to it.
