GODWIN DIARY 17.12.1793 at Woolwich (visiting Muir & Reid in prison hulks) / 28.9.1795 sup at Mrs Johnston's w miss Godwin; Young & Campbell (the top point in the semi-colon between miss Godwin and Young is very tiny, and there is no 'meet', 'adv' or 'see' as Godwin usually applies to names, so Young & Campbell may have been at Mrs Johnston's, or seen just afterwards)
Campbel 27.4.1801 at RA exhibition. In Godwin's 1796 list for 1801 Campbel Thos. This was clearly the poet Thomas Campbell DNB 1777-1844 though not coded to him on GD website. It was the only Campbel entry in Godwin's diary that year. According to the DNB Campbell came "home" (from Europe) in March 1801. There were no artists named Campbell exhibiting at the RA that year. The plain Campbels after this that the GD website hasn't coded to Thomas Campbell the poet were 14.3.1802 Campbel & Wood call / 15.3.1802 Campbel at Fuseli's lecture / 25.3.1802 call on Campbel PH / 30.4.1802 Campbel & Wood dine / 16.5.1803 adv at theatre / 22.8.1808 dine at Campbel's, Sydenham with T(homas) T(urner) / 24.4.1816 Campbel dines (in Edinburgh) / 26.1.1818 call on (Campbell &) Bowden
Of these for Campbel PH see my entry Campbell of 1785, where I suggest PH may have stood for Political Herald, but it perhaps more likely stood for Pleasures of Hope (Thomas Campbell's collection of poems} in which case it clearly meant the poet. The other entries in 1802 were probably all Thomas Campbell the poet. See Wood, James for his connection to Campbell via Lumsden; the entry at Fuseli's lecture was the day after the call of Campbell and Wood. The meeting at the theatre in 1803 was quite likely Thomas Campbell too. The Sydenham Campbell was very likely Thomas Campbell as he leased a house there in 1804 for 21 years (Life and Letters of Thomas Campbell by W Beattie 1849 vol 1 p473). The two 1818 entries, one in Edinburgh and one in brackets, I haven't yet looked closely enough at.
