We read about patrimony, evergetism, and other interesting practices of the ancient Romans.
Also, it is interesting that the Romans regarded the gods as merely one step above the humans, who were in turn seen as one step above animals. So, the cultured Romans did not believe in a servile relationship with gods unlike the peoples of Eastern regions of those times.
Slavery was seen as quite natural and part of daily life, although some of the followers of stoicism later on did have reservations with this practice.
All these and other fascinating details can be gleaned from the fascinating History Of Private Life. This is a multi-volume work encompassing periods all the way from ancient Rome to the modern day.
