If we consider the classical period, say 500 BCE to 500 CE (where CE = common era = AD), India was more advanced in many fields, such as mathematics - including the invention of ‘Arabic’ numerals and zero -, grammar and phonetics, astronomy, botany, logical inference, metallurgy - steel for blades, smelting of zinc -, banking and mass production of cloth exports manufactured using various printing processes. Rome was ahead in architecture and engineering - bridges, aqueducts and public buildings, water wheels, road building - as well as military technology and organisation.

如果我們考慮到是古典時期公元前500年到公元500年(CE =公歷紀元=公元),印度在許多領域更為發達,如數學——包括阿拉伯數字和零的發明,語法和語音學、天文學、植物學、邏輯推理、冶金-鋼葉片、冶煉鋅、銀行業和大規模生產服裝出口,使用多種印刷工藝。羅馬在建筑和工程方面領先——比如橋梁、溝渠和公共建筑、水輪、公路建設——以及軍事技術和統治機構。

Let me talk in more detail about that quintessential Roman speciality: the arch.


India had advanced stoneworking techniques, but did not use them to build arches, which had been known in the Middle East since great antiquity - the earliest surviving example is the Bronze Age arched Canaanite city gate of Ashkelon in modern-day Israel, dating to c. 1850 BCE - but not used much except by Romans until the Arabs and Persians picked up on them. In Mesopotamia they were mostly used for drains back then.

印度有先進的石料加工技術,但沒有使用它們來建造拱門,這在中東自古就為人所知——現存最早的例子是青銅時代的拱形迦南城門,在今天的以色列,可追溯到公元前1850年- - -但在阿拉伯人和波斯人注意到他們之前,羅馬人很少使用它。在美索不達米亞,當時石頭主要用于排水溝。

But then in 350 CE, the Sassanian emperor built a magnificent catenary vault to cover the audience chamber in his new new palace at Ctesiphon. The catenary vault mimics the shape of a hanging chain (Latin catena) but upside down, and requires no buttressing, which is why it is still standing. This was apparently first used in this building, not in Rome. (The catenary arch was later used by Christopher Wren in St. Paul’s Cathedral, and is used in the Sagrada Familia in Barcelona.)



Most ancient Indian temples used corbelled arches and domes, in which each course of a wall is cantilevered out from the lower course until they meet in the middle. This required an equal weight of masonry on the other side to balance, so the buildings were absolutely massive, with little interior space and almost no light. The Bhitargaon temple (450 AD) and Mahabodhi temple (7th century AD) built in by Gupta Dynasty, included true arches, but the technique was not picked up by the architectural style as a whole.


Indians kept building temples this way even after the Muslim invaders came building their domed mosques, until this day. The point of the Indian temple was not to shelter people. All the interior space needed was enough to house one or more murtis, and to allow a few pandits to make offerings. The point of the temple was to provide an ostentatious outwards display, to communicate various things, local history, legends, etc, in the various decorations, and to let the deity know that those who paid for this really, really appreciate his or her support. So there was no real reason to adopt the true arch and dome for monumental architecture.


This is a temple ‘shikhara’ with corbelled construction.



I also provide a picture of the Mahabodhi Buddhist temple, which has a true dome, below. I am sure that you will agree that Indian temple building did not really need the true dome.



This experience supports the answer given by Robert Maxwell. Societies develop technology that they need to fit within the social and economic framework.

這個經驗支持Robert Maxwell給出的答案。社會發展他們需要的技術以適應社會和經濟。

It is worth pointing out that stone arches were used in China in ancient times, the oldest surviving example Being the Anji Bridge dating from around 600 CE. This is not a rudimentary arch. On the contrary it is a fairly sophisticated open-spandrel segmental arch bridge built entirely of stone. The basic principle of the open-spandrel segmental arch bridge ways applied in Hadrian’s Bridge over the Danube built from 103 to 105 CE by Apollodorus of Damascus, but he used timber arches, each spanning 38 metres.


This style of timber arches on stone bases has been much used in the Far East since. To me it seems that a stone bridge might be fine in the dry Mediterranean with its small streams, but would have been prohibitively expensive spanning the mighty Danube, especially as great rivers have a tendency to wash out bridges as the Danube did Hadrian’s bridge a few decades later, and as has been the fate of a great many bridges in China over the years.


Here is a beautiful example of a open-spandrel segmental timber arch bridge from Japan: the Kintai Bridge in Yamaguchi Prefecture, built in 1673. The pic shows one pier and the underside of the arch.



Interestingly, the principle of the true arch was independently invented in pre-Colombian Meso-America, as well as by the Inuit (‘Eskimos’) in the humble igloo.
