Signed at end: Modena, 18. agosto 1785 ... Girolamo Tiraboschi.
The addressee of the letter is Tommaso Maria Mamachi (cf. Diz. di opere anon. e pseudon. di scrittori ital. / G. Melzi), who undertook to rewrite the text of Tiraboschi's Storia della letteratura italiana without his permission. Tiraboschi protested the revisions in an earlier letter, with the result that Mamachi's changes, published in the Rome, 1782 edition, were printed in the form of notes to Tiraboschi's text. Cf. Tiraboschi's Storia, v. 9 (1825), p. xviii-xxi. Tiraboschi included the text of both letters to Mamachi in v. 8 of later, authorized editions of his Storia della letteratura italiana, along with similar correspondence with his critics.
