Piranesi in Ghent is an exhibition, a catalogue and a symposium. It is also a telling story in the recent scholarship and recurring ‘fashionable’ re-discoveries of Piranesi’s work. It is a funny story, a serious cultural enterprise that begins, like all good love stories, by chance. But there’s more here: scholarly passion, intellectual curiosity, design and experimentations: as well as reproductions, plates and debates, and a lot of challenging hypotheses and development possibilities. This is indeed a very Piranesian story and, as in Piranesi’s work, here the less visibly obvious is worthy of the greatest attention, because it reveals more, much more indeed, than what appears at first.

This chapter focuses on the barriers to all students achieving their full potential that are rooted historically in the disparate understanding of geography itself. How the subject is delivered is scrutinized from both the historical and a pragmatic perspective but, importantly, the link between past and present is highlighted as key if the subject is finally to be embedded as a cohesive, mainstream subject that allows students to fully understand the realities of their world.

Pollen, microscopic charcoal, palaeohydrological and dendrochronological analyses are applied to a radiocarbon and tephrochronologically dated mid Holocene (ca. 8500–3000 cal B.P.) peat sequence with abundant fossil Pinus (pine) wood. The Pinus populations on peat fluctuated considerably over the period in question. Colonisation by Pinus from ca. 7900–7600 cal B.P. appears to have had no specific environmental trigger; it was probably determined by the rate of migration from particular populations. The second phase, at ca. 5000–4400 cal B.P., was facilitated by anthropogenic interference that reduced competition from other trees. The pollen record shows two Pinus declines. The first at ca. 6200–5500 cal B.P. was caused by a series of rapid and frequent climatic shifts. The second, the so-called pine decline, was very gradual (ca. 4200–3300 cal B.P.) at Loch Farlary and may not have been related to climate change as is often supposed. Low intensity but sustained grazing pressures were more important. Throughout the mid Holocene, the frequency and intensity of burning in these open Pinus–Calluna woods were probably highly sensitive to hydrological (climatic) change. Axe marks on several trees are related to the mid to late Bronze Age, i.e., long after the trees had died.
