It is uncertain, at what time our author was married, but, it is supposed, that his first wife Anne, daughter and heir of Edward Banks, esq; was dead before he fell in love with lady Dorothy Sidney, daughter to the earl of Leicester, whom he celebrates under the name of Sacharissa. Mr. Waller's passion for this lady, has been the subject of much conversation; his verses, addressed to her, have been renowned for their delicacy, and Sacharissa has been proposed, as a model to succeeding poets, in the celebration of their mistresses. One cannot help wishing, that the poet had been as successful in his Addresses to her, as he has been in his love-strains, which are certainly the sweetest in the world. The difference of station, and the pride of blood, perhaps, was the occasion, that Sacharissa never became the wife of Waller; though in reality, as Mr. Waller was a gentleman, a member of parliament, and a person of high reputation, we cannot, at present, see so great a disproportion: and, as Mr. Waller had fortune, as well as wit and poetry, lord Leicester's daughter could not have been disgraced by such an alliance. At least we are sure of one thing, that she lives for ever in Waller's strains, a circumstance, which even her beauty could not have otherwise procured, nor the lustre of the earl of Sunderland, whom she afterwards married: the countess of Sunderland, like the radiant circles of that age, long before this time would have slept in oblivion, but the Sacharissa of Waller is consigned to immortality, and can never die but with poetry, taste, and politeness. Upon the marriage of that lady to lord Spenser, afterwards earl of Sunderland, which was solemnized July 11, 1639, Mr. Waller wrote the following letter to lady Lucy Sidney, her sister, which is so full of gallantry, and so elegantly turned, that it will doubtedly give pleasure to our readers to peruse it. MADAM,
