The original Greek kistē meant basket. I put a search for kistē + archeology and got a doctoral thesis from the University of Glasgow
"3.11.1 Basket Vase
This is presumably a kalathos,the name used for
a vessel shaped like an inverted bell or basket. There are other types of basket vase which are mentioned by the ancient authors, i.e. kibōtos (κιβωτός), kistē (κίστη) and phormos.
The term was certainly used in conjunction with wicker baskets i
n antiquity. Production of kalathoi is known from the Protogeometric period (or earlier) onwards.

Its presence at the Kabeirion is probably due to a dedication but whether the offering was the vessel itself or its contents is unclear.
We know that baskets played a role in ritual by carrying dedicatory goods to a sanctuary and that they could be made from materials other than wicker."
