Thanks. Some great info at that page. We were discussing the “wishing well” idea recently. This page says “The fact that this vessel has survived in its entirety suggests that it may have been deliberately placed in the waterhole, perhaps as a closing deposit for the well. Exactly why people in the Iron Age often used pots as offerings in this way is something of a mystery.”
A “closing deposit” is a new idea (at least to me) that nobody pitched in the recent discussion.
It’s interesting that the best place to find whole pots is in graves. Every day pottery ended up broken and discarded. Makes a lot of sense.
