In Peter's Letters to his Kinsfolk (1819) the young John Gibson Lockhart (under the guise of an elderly Welsh physician) portrayed and analysed the society of Regency Glasgow and Edinburgh in terms of German nationalist and Romantic criticism. Focusing on the networks of the law, the church, the universities, fine art, antiquarianism, literature, theatre, and periodical culture he provided a series of brilliant, sometimes serious and sometimes satirical, portraits of the most notable characters of the day and the institutions they represented, and his text is accompanied by a series of portrait engravings and of vignettes of significant moments in his tour. This edition presents the first complete text of this widely-allusive work published since 1819, together with the substantial notes that a modern reader requires to understand it fully. The editorial apparatus also comprises a detailed index and an essay on the contemporary illustrations.
