In Book XIX of the Odyssey, Penelopē said that "dreams ... which issue forth from the gate of polished horn bring true issues to pass, when any mortal sees them." (Here, there may be a pun[16] of /KRainō/ 'I fulfill' with /KeRas/ 'horn'.) Likewise, Herodotos distinguished[17] /oneiros/ (or /enar/) as "the prophetic, God-sent dream" from /en-upnion/ "the non-predictive dream".
