“…At its most fundamental level, maritime archaeology may thus need to develop theories capable of dealing with such diametrically-opposed perceptions, in so much as it is capable of doing this (Cooper, 1975;Frake, 1985;Gell, 1985;Noble & Hogbin, 2001). Work upon such areas helps give a radical new spin to long-running debates such as those about Pleistocene voyages to Australia (Bednarik, 1997;Bednarik, 1998;Bednarik et al, 1999): 'we'-land-based, fundamentally fearful of the sea-perceive these voyages as virtually impossible: cultures that perceive of both sea and land together as a largely undifferentiated whole arguably would not (Broodbank, 1989;Cherry, 1990). Such theories also allow a better understanding of other long-distance, 'bluewater', seafaring by small groups and even individuals, and both physical and psychological demands (Lewis, 1994;Noble & Hogbin, 2001), particularly early voyages in the North Atlantic and Arctic during the period of Norse voyaging, the evidence for the extent of which is only just beginning to be appreciated (McGrail, 1989;McGovern, 1990;McGhee, 1992;Wallace, 1999;Ingstad & Ingstad, 2000;Seaver, 2000;Herbert, 2003).…”
