Orlando, born in the 16th century and at home in the 17th and 18th, seems to suffer aesthetic culture shock when confronted with the curlicued ornamentation-run-riot of the Victorian era. This is a description of an excrescence-encrusted monument where every conceivable symbol has been piled on. On this basis, I take the ‘plaid-like juxtapositions’ to suggest strongly contrasted elements, while also echoing the Victorian romance for Scotland.
‘The incongruity of the objects, the association of the fully clothed and the partly draped, the garishness of the different colours and their plaid-like juxtapositions afflicted Orlando with the most profound dismay.’
