Note 12 — LECTURE I. ARCHITECTURE.
Reading edition
It has been objected to this comparison that the form of the pediment does not properly represent that of the rocks of the Trossachs. The objection is utterly futile, for there is not a single spire or pinnacle from one end of the Trossachs to the other. All their rocks are heavily rounded, and the introduction of the word "spire" is a piece of inaccuracy in description, ventured merely for the sake of the Gothic image. Farther: it has been said that if I had substituted the word "gable," it would have spoiled the line just as much as the word "pediment," though "gable" is a Gothic word. Of course it would; but why? Because "gable" is a term of vulgar domestic architecture, and therefore destructive of the tone of the heroic description; whereas "pediment" and "spire" are precisely correlative terms, being each the crowning feature in ecclesiastical edifices, and the comparison of their effects in the verse is therefore absolutely accurate, logical, and just.
