Yes, If an infant was deformed, or considered less than perfect in some way, I understood the practice was to bury them in a jar as a way to dispose of them.
The Viking upper classes had similar ideas: after birth the child was presented to the father; if he considered that it simply wasn’t up to scratch in any way, then out it went. (The babes were just abandoned in the forests).
Life was tough in those days - slavery was widespread - and they couldn’t afford to support the less able!
Yes. Infanticide was practiced by many different cultures....I lived in Japan and visited just such a “burial” temple dedicated to infants only. In Hawaii, they used to also dispose of “less than perfect” children. The practice is worldwide. It surprised me at the obfuscation lens placed upon this article. It is a growing trend to see the past through “today’s eyes”. It gives a false narrative of history. We are doomed to repeat what we forget.
