The burial ground at Liffride is 40x25 meters and has three round paving and two shipwrecks. The northern setting of ships belongs to the transition between older and younger Bronze Age, 1220-970 BC, while the southern belongs to the younger Bronze Age, 700-500 BC. However, most ship settlements in Sweden are from the Vendel era (colonization period) and the Viking age, ie on the other side of Christ's birth, for example, the well-known Ale stones that are from the Vendel period, between 400-900 years AD, but when you look at Gotland they are often a couple of thousand years older, like those in Liffride.
To place the Liffride ships in time, we can say that Homeros and meandering ships are from 800 BC, the greatest moral philosopher of all time, at least if you read Walt Whitman, but Mosen is contemporary with the Northern shipwreck, the oldest. Odysseus, Polyfemos and the guys would not see the light of the world for many hundreds of years other than when people in Alskog started to brag about their loved ones dead in Liffride.
