Peter Kees Bol sa zameriava na kultúrne elity Číny od 7. do 17. storočia a skúma ich prechody a využitie klasických textov. Jeho práca sa vyznačuje hlbokým porozumením historickým posunom a intelektuálnym dejinám, pričom využíva aj moderné geografické informačné systémy na analýzu dlhodobých historických trendov v čínskej histórii. Bolov prístup kombinuje tradičný historický výskum s inovatívnymi technológiami, čím ponúka jedinečný pohľad na vývoj čínskej kultúry a spoločnosti. Jeho dielo je zásadné pre pochopenie zložitosti čínskej intelektuálnej histórie a jej geografického kontextu.
In premodern China, Korea, Japan, and Vietnam, just as in the far less culturally cohesive countries composing the West of the Middle Ages, enslavement was an assumed condition of servitude warranting little examination, as the power and profits it afforded to the slaver made it a convention pursued unreflectively.
Bridges, the least known and understood of China's many wonders, are one of its most striking and resilient feats of architectural prowess. Chinese Bridges brings together a thorough look at these marvels from one of the world's leading experts on Chinese culture and historical geography, Ronald G. Knapp.While many consider bridges to be merely utilitarian, the bridges of China move beyond that stereotype, as many are undeniably dramatic, even majestic and daring. Chinese Bridges illustrates in detail 20 well-preserved ancient bridges, along with descriptions and essays on the distinctive architectural elements shared by the various designs. For the first time in an English-language book, Chinese Bridges records scores of newly discovered bridges across China's vast landscape, illustrated with over 400 color photographs, as well as woodblock prints, historic images, paintings and line drawings.
