In the National Museum today I looked at the two whalebone caskets. They are about 15th century in date, from the West Highlands – similar caskets appear on the stone slabs such as the one from Keills, and it has been suggested that the caskets were used to store documents such as charters and land-grants.
I was interested to look at the interlace panels; they seem similar to the interlace on the Trinity College harp forepillar. There is also some similarity with the small sections of interlace on the Queen Mary harp forepillar.
