The dedicatee Thomas Barrett has apparently not been identified. He may have been one of the following: (1) Thomas Barrett-Lennard, 17th Baron Dacre (1717-1786), who was in Rome 1749-1751 (Ingamells, op. cit., pp. 53-54), and still alive but presumably back in England when Piranesi concluded this series of prints; or (2) Thomas Barrett (1743 or 1744-1803), described in Alumni Cantabrigienses as admitted as Fellow-Commoner aged 18 at Trinity College Cambridge, 7 March 1762; well known collector of pictures and curiosities; d. unmarried Jan 8, 1803, aged 59 at Lee; not in Ingamells, op. cit. as having visited Italy), or (3) Sir Thomas Barrett-Lennard, 1st Baronet (1761-1857), the son of Thomas Barrett-Lennard, 17th Baron Dacre: he was a Fellow of the Society of Antiquaries of London, but there seems to be no evidence that he visited Italy (and he was aged only 16 when this series of etchings was concluded)
