Kapnobatai

Kapnobatai or capnobatae, meaning "those who walk on/in smoke/clouds" was one of the names given to the Mysians of Thrace who practiced the dietary restriction of not consuming living things, thus living on milk and honey. The description is given by Strabo who attributes the information to Posidonius.
Mysians are understood as a people who originally from Asia Minor, but those living in Thrace have become confounded with the Getae, according to Strabo. As such, some commentators refer to them as Dacian priesthood.
