Ain't that wonderful?
I sometimes like to imagine what a culture looked like at the street level, and knowing about a common type of pottery goes a long way in helping to do that. In addition to the archeological article I'll find here and there, things like Malalasekera's "Dictionary of Pāli Proper Names" have enough fun little details to help me get a better picture.
I don't know if the original begging bowls would have been that black ware, but for now I'll let myself envision them that way.
