In this 2015 presentation (which we discussed this week in my Forbidden Archaeology class), Joe Taylor claims the following (starting about 55:20):
"Enoch says there were men . . . I think he says 1200 feet tall, or ells, or 450 feet, you know. I think there's evidence of a 450-foot-tall man that's been found. There's a tibia that used to be used as a bridge somewhere in the Middle East, somewhere. Four hundred and fifty feet tall. There's a tiba,a human tibia, supposedly . . . there's no dinosaur on the whole earth with a tibia more than 10 feet long. Maybe there will be, but a 450-foot man has a 100-foot-long tibia. So let's say he's buried in the Flood, well there's a lot of bulk, a lot of fat and stuff around that. Maybe he's covered in a hundred feet of mud, well then in a few hundred years that erodes away. In a few thousand years he's down to his bones. They still have a lot of fat in them. And this one bone is long enough to make a bridge with. Okay, so . . . he had to have been buried in the Flood, so maybe that report is true. Maybe there were men 450 feet tall."
First, I found this 14th-century account by Bavarian traveler Johann Schiltberger (English translation published in 1879 in The Bondage and Travels of Johann Schiltberger; I copied this text from Jason Colavito's "Fragments of Giants" page):
"It is to be noted, that in Egypt there was a giant, who was called in the Infidel tongue, Allenklaisser. In this country is the city called Missir, but the Christians call it Kayr [i.e. Cairo], and it is the capital of the king-sultan. In this same city are twelve thousand baking ovens. Now the said giant was so strong, that one day he brought into the city a bundle of wood to heat all the ovens, and one bundle was enough; each baker gave him a loaf, which makes twelve thousand loaves. All these he ate in one day. The shin-bone of this giant is in Arabia, in a valley between two mountains. There is a deep valley between the rocks, where flows a river at such a depth that no person can see it, one only hears its rush. It is in this same valley that the shin-bone of the giant serves as a bridge; and whoever comes there, whether they are riding or on foot, must pass over this shin-bone. It is also on a road where traders pass, coming and going, because the defile is so narrow, that people cannot pass by any other way; and the Infidels say that this bone is one frysen [i.e. parasang—about 3 miles] in length, which is equal to an arrow's flight, or more. There, a toll is taken from traders; with the same, they buy oil to anoint the bone that it may not rot. It is not a long time since a king-sultan had a bridge built near the bone; it is about two hundred years [ago], according to an inscription on the bridge. When a lord comes there with many people, he passes over the bridge, and does not pass over the bone; but whoever wishes to pass over this wonder, may do so, that he may say of it that in this country there is an incredible thing, and which is nevertheless surely true. And if it were not true, or had I not seen it, I would not have spoken or written about it."
"They had several audiences with Bereke, who asked them many questions about Egypt, about elephants and giraffes, and one day asked if the report was true that there was a giant's bone thrown across the Nile which served as a bridge. The envoys replied that they had not heard of such a thing.*
*In regard to this report, M. Quartremere tells us it was founded on a very ancient Arabic tradition. In "The History of the Conquest of Egypt," written by Abd al Hakam, we are told that a giant named Auj, having been killed by Moses, his body fell across the Nile and made a bridge. Schlitberger, the Bavarian traveller, tells us that there was a bridge in Arabia made out of a giant's leg bone, which united two rocks separated by a deep chasm. Travellers to Arabia had to cross this bridge. A toll was charged, from the proceeds of which oil was bought with which to oil the bone, and thus prevent it decaying. (Op. cit., 218. Note.)."
"We read in Abd-el-Hakam's history of the conquest of Egypt (Makrizi by Quatremere, I, i, 218), that the body of a giant killed by Moses fell across the Nile and served as a bridge. With this legend may be associated Schiltberger's tale, and his credulity need not be wondered at when we consider, that in the 13th century the story was thought worthy of being related; and some there were even bold enough to tell it to the powerful ruler of the Golden Horde, Bereke Khan, who enquired of the ambassadors sent to him in 1263 by the sultan Bibars, whether it was true that the bone of a giant, laid across the Nile, was being used as a bridge! The ambassadors, who had been probably selected from among the most enlightened of the sultan's minsters, replied that they had never seen it, and answer that may have been elicited by the nature of the question, because the strange bridge seen by Schiltberger must have been in Arabia and not in Egypt. It united two rocks separated by a profound ravine in the depths of which coursed a torrent, and as it afforded the only practicable means for crossing the ravine on the high road, travelers were obliged to pass over it.
"I cannot believe that these topographic details were invented by Schiltberger, and am therefore inclined to think that he alludes to the neighborhood of the fortresses of Kerak and Shaubek, places that acquired considerable importance during the Crusades in consequence of their admirable situations. They are easily identified with "Crach" and "Sebach" mentioned by De Lannoy . . .
"Shaubek, the "Mons regalis" of the Crusaders, thirty-six miles from Kerak, was also a strong place. Burckhardt tells us that a ravine, three hundred feet in depth, encircles the citadel . . .
"According to an Arabian author quoted by Quatremere (l. c. II, i, 245), the road near these two cities was so peculiar that it could have been held by one man against a hundred horsemen. Another reason for the supposition that the bridge seen by Schlitberger was in one of these passages, lies in the fact that the same writer includes the tomb of Iskender among the holy places of pilgrimage in this ancient country; but he does not determine the individuality of that Iskender.
On the hypothesis that "Allenklaisser's" limb was near the tomb of Iskender, I should be inclined to look in the same locality for the bridge that was constructed, according to the inscription it bore, two hundred years before Schiltberger saw it. . . . This circumstance, no doubt, induced the "king-sultan" to order the construction of a bridge for keeping up communication between two parts of his kingdom, the new bridge being near the old one that was kept smeared with oil, a condition that had the effect of persuading the guileless Bavarian that it was indeed a gigantic bone."
