7 notebooks created by J. H. Middleton to document his travels in Greece, Italy and Egypt and his studies of classical architecture in antiquity. These notebooks were going to form the basis of a companion book to his publication on Rome, focussed on the topography of ancient Athens. They mainly consist of architectural and topographical drawings made in situ during his travels in the early 1890s.
Professor Ernest Gardner was appointed by the Society of the Promotion of Hellenic Studies to prepare the material for publication after Middleton's untimely death in June 1896. Middleton's measured drawings and plans were revised by Thomas D. Atkinson in 1899, who was the achitect then in residence at the British School at Athens. Gardner's footnotes to the volume detail the published topographical underpinnings of many of Middleton's own drawings, especially Penrose 1851, Principles of Athenian Architecture, which were then given further nuance by JHM from personal observation on the ground.
1 notebook somehow related to the Middleton material but not created by him but compiled some thirty years after his death by someone with similar academic interests.
