perikeimai describes something lying or being set around a person, whether a physical object or an encompassing condition.

The attested usage most often concerns a physical object around a person, including a chain and a millstone at the neck; the remaining instances extend the same surrounding relation to a cloud of witnesses and to weakness encompassing a person.
