18. In north-eastern Louisiana is an archaeological site with finds dating back 3,200 years in terrain filled with mounds that can only be manmade. The largest, Bird Mound, is seventy-two feet high and would require eight million baskets of sand weighing fifty-five pounds each to create. Archaeological research has shown that its construction took no more than a few months and was the concerted labour of at least ten thousand workers. See Anthony L. Ortmann, ‘Building Mound A at Poverty Point, Louisiana: Monumental Public Architecture, Ritual Practice, and Implications for Hunter-Gatherer Complexity’, Geoarcheology (7 December 2012).

60. In Persian and Roman times, state expansion was already making the world incrementally safer. Though it sounds like a paradox, there is a logical explanation. As countries and empires grew, more of their citizens lived further away from borders. It was at borders that wars were fought; life was more peaceful in the interior. Illustrative of this is the Pax Romana (Roman Peace), a long period of stability secured by the great campaigns of the mightiest Leviathans. In this sense, at least, Hobbes was right: better one all-powerful emperor than a hundred frustrated petty kings. See Turchin, Ultrasociety, pp. 201–2.

12. Diamond owes a debt to historian Clive Ponting, who wrote about Easter Island in his book A Green History of the World (1991). On the first page, Ponting describes the island as Roggeveen found it: ‘about 3,000 peopl
e living in squalid reed huts or caves, engaged in almost perpetual warfare and resorting to cannibalism in a desperate attempt to supplement the meagre food supplies available on the island’.

25. The archaeologists Carl Lipo and Terry Hunt think some statues were ‘walked’ vertically into place using ropes, not trees, the same way you might move a refrigerator or washing machine. This method also requires fewer people. See Carl Lipo and Terry Hunt, The Statues that Walked. Unraveling the Mystery of Easter Island (New York, 2011). Lipo and Hunt’s story was popular in the media, but Jan Boersema still believes most of the statues were rolled on tree trunks by big groups of people, because efficiency was not the motivating factor behind such collective work events.

Didn’t the rats pose a problem for farming on the island? Boersema thinks not. ‘Most food crops were tubers,’ he explains, ‘which grow beneath the soil. And the bananas grew on small trees which made them less appealing to rats.’

39. Some scientists believe the statues fell down during an earthquake. Others think some moai were laid down over the graves of deceased chieftains. See Edmundo Edwards et al., ‘When the Earth Trembled, the Statues Fell’, Rapa Nui Journal (March 1996).
40. This also gave rise to the ‘Birdman Cult’, an annual competition between young men representing different tribes to snatch the first sooty tern (a seabird) egg of the season. Exactly when this tradition arose is unknown, but it was probably before Roggeveen’s arrival. This cult was also linked to the moai. After the competition, the newly elected leader went to live in a house outside the stone quarry where the statues were carved. When Roggeveen arrived in 1722, the moai still had a definite ceremonial function, even if it was no longer possible to transport them (using trees) and even though the Birdman Cult probably already existed.
