This summary ground plan of the Monument, London, is annotated with figures and other notes written both horizontally and vertically relative to the general foliation of the sketchbook, as if Turner were pacing around it. The figures include ‘26’ and ‘24’ near the base, ‘1 ½’ at the top centre, ‘[...] yards’ diagonally towards the top right, ‘20’ towards the top left, what may be an ‘S’ towards the bottom left and possibly ‘8’ or ‘18’ within the plan. The pedestal is actually about 21 feet square and 40 feet high and the plinth 28 feet square, with the shaft of the column around 15 feet in diameter and some 120 feet high1 (about 6.5, 12, 8.5, 4.5 and 36.5 metres respectively).
Maurice Davies relates this and the studies on folios 12 verso–13 recto, 19 verso, 20 recto, 31 recto and 34 recto (D07977, D07978, D07988, D07989, D08002, D08005) to Turner’s first perspective lecture, delivered at the Royal Academy in January 1811 (see the Introduction to the sketchbook); Turner discussed the ‘flaming ball’ surmounting the Monument, and the distance from the base at ground level from which it could be viewed,2 in relation to his large watercolour diagram ‘4’ showing both the whole structure and the upper stages from below (Tate D17122; Turner Bequest CXCV 151). For further details of the structure see under folio 12 verso (D07977).
