"Within Scandinavia, the Ringerike style is usually assigned to the late tenth and first half of the eleventh century on account of its inclusion in coin-dated hoards of this date (Wilson 1995, 182-83).
The style was broadly contemporary in England, where it is likely to have been introduced following the accession of the Danish King Cnut in 1016.", from Kershaw (2011).
