The Romans ingenious use of (the arc and key stoning/concrete/entablatures/columns) was instrumental in the construction of the great cathedrals of Europe, 1000 years later

Answer 1

The Romans' use of the arch and keystone in their architectural designs allowed for greater stability and strength in their structures, enabling them to create larger and more elaborate buildings. The use of concrete, which they invented, also played a critical role in the construction of their buildings, providing a durable and versatile building material that could be molded into a variety of shapes.

Additionally, the Romans' use of entablatures and columns in their architecture helped to create visually stunning and structurally sound buildings. These elements provided support for the roof and upper levels of their structures, while also adding decorative elements to their design.

The techniques and innovations developed by the Romans in their architecture laid the groundwork for the construction of the great cathedrals of Europe, which drew inspiration from Roman design principles. By incorporating elements such as the arch, concrete, entablatures, and columns into their own designs, medieval architects were able to create monumental buildings that continue to stand as testaments to the ingenuity and skill of the Romans.
