The ancients thought that this stone had the power of dispelling drunkenness in all who wore or touched it, and hence its Greek name formed from a , "privative," and methuo , "to get drunk." Its Jewish name, ahlamah' , was derived by the rabbins from the Hebrew word halam , "to dream," from its supposed power of causing the wearer to dream.
