Rhaphanidosis is the act of insering a radish (ot other root) into the anus. Aristophanes mentions that it was used as a form of punishment in Ancient Greece in the 5th and 4th centuries BC. In Athens, it was used to punish adultery. Later it also seems ot have been used to punish promiscuity and  sodomy.

Aristophanes mentiones it in his work The Clouds. There is some debate, if anyone was ever punished that way. Poepl have said that it could be seen as public humiliation in general.
