Jerrold Ziff has identified these notes as free transcriptions from the 1598 English edition of Giovanni Paolo Lomazzo’s
Tracte Containing the Artes of Curious Paintinge Carvinge & Buildinge (see the sketchbook Introduction).
1The first paragraph comes from chapter III, ‘The Definition of Perspective’, of ‘The Fifth Booke: Of the Perspectives’, page 189, with Turner’s note to himself, ‘look at Moxon’, prompted by Lomazzo’s listing of various forms of glass such as ‘concave, rounde, plaine’; a copy of Joseph Moxon’s
Practical Perspective, or Perspective Made Easy ... (London 1670) was acquired by Turner at an unknown date.
2The second paragraph comes from chapter V, ‘Of the Manner of Seeing In Particular’, page 192, and the third from chapter VIII, ‘Of Distance’, page 200, where Lomazzo advises: ‘That the person which beholdeth, stande off from the object or wall seene, three times the height thereof’. The last derives from chapter XXI, ‘Of Perspective in General, According to Io Bramantino a Perspective Painter and Architect’, page 215:
I remember I have read something concerning the Perspectives of Bartholomeus called Bramantino a Milanese, which I propose to set down in this place; ... Howbeit I am not yet resolved to publish a certain treatise I have of the Persepectives compiled by Bernade Zenale in the time of the great Plague ... marry this much I will promise, to put forth heereafter, a certain work of Vincentius Foppa a Milanese
