"We were approaching the famed Pillars of Hercules, and already the African one, "Ape's Hill," a grand old mountain with summit streaked with granite ledges, was in sight. The other, the great Rock of Gibraltar, was yet to come. The ancients considered the Pillars of Hercules the head of navigation and the end of the world. The information the ancients didn't have was very voluminous. Even the prophets wrote book after book and epistle after epistle, yet never once hinted at the existence of a great continent on our side of the water; yet they must have known it was there, I should think." (page 64) 

"Do you see that there hill out there on that African coast? It's one of them Pillows of Herkewls, I should say--and there's the ultimate one alongside of it." 

"The ultimate one--that is a good word--but the pillars are not both on the same side of the strait." (I saw he had been deceived by a carelessly written sentence in the guidebook.) 

"Well, it ain't for you to say, nor for me. Some authors states it that way, and some states it different. Old Gibbons don't say nothing about it--just shirks it complete--Gibbons always done that when he got stuck --but there is Rolampton, what does he say? Why, be says that they was both on the same side, and Trinculian, and Sobaster, and Syraccus, and Langomarganbl----" 

"Oh, that will do--that's enough. If you have got your hand in for inventing authors and testimony, I have nothing more to say--let them be on the same side." (Page 70).

I suspect the Oracle was confusing the issue of which was the original southern pillar, Jebel Musa or Monte Hacho
