The following are some early mentions (and descriptions) of ‘romantic love’ in English literature. Note the continuity of courtly love themes from the Middle Ages such as belief in the purity of women and their elevation above men, along with male supplication, chivalry and long-suffering, and of the ultimate extravagance of love – PW
1737:
“Farewell, farewell forever. She left me, with how much concern upon my heart, as it was beyond what I ever felt, it is beyond what I can ever express. Tho’ I was assur’d her reproach was unjust, yet from the principles of affection that gave occasion to it, it affected me. I struggled long between romantic love and prudent conduct: one day I resolv’d to fling myself at her feet the next, and give a proof of my love by ruining myself in marriage ; but the next I thought it better to see her Father again, and strive if…” [The London Magazine; Or, Gentleman’s Monthly Intelligencer, 1737]
1741:
“But I think the tragedy may receive a wonderful force, should its authors, without minding that giddy Romantic Love which makes such havoc in their plays, follow only the true philosophic Ideas of antiquity.” [An historical and critical account of the theatres in Europe, Luigi Riccoboni – Printed for T. Waller, 1741]
1749:
“This novel is altered from one published in the year 1762 The Author, perceiving many material defects in the original work, particularly that the story was too simple to be very interesting, too concise to admit of much exemplification of character, and too much in the usual strain of romantic love.” [The Monthly Review, Volume 53, Ralph Griffiths, George Edward Griffiths, 1749]
1761:
“There is no resisting the impetuosity of romantic love. Like enthusiasm it breaks through all the restraints of nature and custom and enables, as well as animates its votaries, to execute all its extravagant suggestions ” [The World – by Adam Fitz-Adam, by Edward Moore, publishe by R. and J Dodsley 1761]
1773:
“The adventures of the Spanish knight [Don Quixote] were written to expose the absurdities of romantic chivalry, so those of the English heroine were designed to ridicule romantic love, and to show the tendency that books of knight-errantry have to turn the heads of their female readers.” [The Critical Review, Or, Annals of Literature, Volume 35, W. Simpkin and R. Marshall, 1773]
1776:
“Reading books of extravagant poetry raises corresponding doubt’s in the mind as they paint all the passions immoderate. Tragedies, such as they frequently are; books of romantic love, and which is fifty times worse, books of romantic intrigues, all tend to disturb the breast of the tender fair one.” [The Lady’s Magazine; Or, Entertaining Companion for the Fair Sex, Appropriated Solely to Their Use and Amusement, Volume 7, G. Robinson, 1776]
1777:
“In this correspondence the two friends encourage each other in the [……?] notions imaginable. They represent romantic love as the great important business of human life, and describe all the other concerns of it as too low and paltry to merit the attention of such elevated beings, and fit only to employ the daughter of the plodding vulgar.” [The Universal Magazine of Knowledge and Pleasure, Pub. for J. Hinton, 1777]
1798:
“I readily grant that in former times this veneration for personal purity was carried to an extravagant height, and that several very ridiculous fancies and customs arose from this. Romantic love and chivalry are strong instances of the strange vagaries of our imagination, when carried along by this enthusiastic admiration for female purity; and so unnatural and forced, that they could only be temporary fashions. But I believe that, for all their ridicule, it would be a happy nation where this was the general creed and practice.” [Proofs of a Conspiracy against all the Religions and Governments of Europe, by John Robison, Philadelphia, 1798]
