[379] 'While Jones' and Boyle's united labours fall:' at the time when this poem was written, the banqueting-house of Whitehall, the church and piazza of Covent Garden, and the palace and chapel of Somerset House, the works of the famous Inigo Jones, had been for many years so neglected as to be in danger of ruin. The portico of Covent Garden church had been just then restored and beautified at the expense of the Earl of Burlington, who, at the same time, by his publication of the designs of that great master and Palladio, as well as by many noble buildings of his own, revived the true taste of architecture in this kingdom.--P. [380] 'Mad Mathesis:' alluding to the strange conclusions some mathematicians have deduced from their principles, concerning the real quantity of matter, the reality of space, &c.--P. W. [381] 'Pure space:' i.e. pure and defaecated from matter. 'Ecstatic stare:' the action of men who look about with full assurance of seeing what does not exist, such as those who expect to find space a real being.--W. [382] 'Running round the circle, finds it square:' regards the wild and fruitless attempts of squaring the circle.--P. W. [383] 'Nor couldst thou,' &c.: this noble person in the year 1737, when the act aforesaid was brought into the House of Lords, opposed it in an excellent speech (says Mr Cibber), 'with a lively spirit, and uncommon eloquence.'

[384] 'Harlot form:' the attitude given to this phantom represents the nature and genius of the Italian Opera; its affected airs, its effeminate sounds, and the practice of patching up these operas with favourite songs, incoherently put together. These things were supported by the subscriptions of the nobility. This circumstance, that Opera should prepare for the opening of the grand sessions, was prophesied of in book iii. ver. 304, 'Already Opera prepares the way, The sure forerunner of her gentle sway.' P. W. [385] 'Division reign:' alluding to the false taste of playing tricks in music with numberless divisions, to the neglect of that harmony which conforms to the sense, and applies to the passions. Mr Handel had introduced a great number of hands, and more variety of instruments into the orchestra, and employed even drums and cannon to make a fuller chorus; which proved so much too manly for the fine gentlemen of his age, that he was obliged to remove his music into Ireland. After which they were reduced, for want of composers, to practise the patch-work above mentioned.--P. W. [386] 'Chromatic:' that species of the ancient music called the Chromatic was a variation and embellishment, in odd irregularities, of the diatonic kind. They say it was invented about the time of Alexander, and that the Spartans forbad the use of it, as languid and effeminate.--W.
