It started in the 5th century and ended in the 15th century.
There was a great migration of Germanic people seeking new lands in western Europe in the late 2nd Century BCE, which put them in collision with the Romans who were expanding control in southern France and in Spain.
Travertine was one of the three types of stone the Romans used for construction. The others were tuff and peperino. I guess you are referring to the 2nd century BC rather than AD. Travertine is a lime stone which is harder than volcanic stones and takes a strong edge and sharper edge far better. Its quarrying probably started in the 2nd century BC and until the 1st century BC it was used selectively. Then it was used as a substitute for white marble in public buildings. It came in use for pavings, steps, door frames, springers of arches, stone corbels, keystones and well heads. Travertine was expensive. It was used for highest quality work and the use of volcanic stone continued. The Romans called it lapis Tiburitinus (stone of tibur) because it was quarried at Tibur (modern Tivoli) 30 km northeast of Rome. Originally the Romans used only tuff, the local volcanic stone, for construction. Then they also used peperino stone. It is harder and more compact than tuff and although it is harder to work, it weathers better.I t was used for the outer face of buildings (the inside part was in tuff). In the 4th century BC it was used in the for statues and other stone artifacts. From the 2nd century BC it was used as a high quality stone for construction. The Romans called the peperino quarried in the Alban Hills area (20 km southeast of Rome) lapis Albanus (Alban stone) and the peperino from Gabii (16 Km east of Rome) Lapis Gabinus.
