   • 1692, Sir Roger L'Estrange, “Fable CCCCLXVI: A Fig-Tree and a Thorn”, in Fables of Æsop and Other Eminent Mythologists, page 441:

     Nay, the very Ostentation of the Thorn, is a Weakness, and I might have said a Vice too; for the Vanity Unhallows the very Virtue, especially where it is Accompany'd with Detraction.
