Milton had no fondness for the Scots and their accent. When the Stuarts ascended the English throne they were followed into England by a swarm of Scots lords and their retainers looking to make their fortune south of the border, raising much resentment in many Englishmen and incidentally introducing them to many alien names for the first time which would later grow familiar.
Milton’s Sonnet 11, On The Detraction Which Followed Upon The Writing of Certain Treatises, was published in 1645. The poet was disgruntled that his latest book, Tetrachordon, or Expositions upon the four chief places in Scripture, which treat of marriage, or nullities in marriage, had sold poorly, with some ‘stall-readers’ apparently balking at the term Tetrachordon ("Bless us”! what a word on a title-page is this!").
The sonnet continues,
................ Why is it harder, Sirs, than Gordon,,
Colkitto, or Macdonnel, or Galasp?†
Those rugged names to our like mouths grow sleek,
That would have made Quintillian stare and gasp;
The rugged names would indeed grow sleek to English mouths as Gordon, Colquhoun or Calhoun, MacDonald and Gillespie.
Quintilian of course was the 1st century Roman whose Institutio Oratoria was the gold standard in matters of style, oratory and rhetoric.
