What is old roman name for Germany?

There wasn't a single, unified "old Roman name" for Germany. The Romans, like the Greeks before them, generally referred to regions by the names of the tribes inhabiting them.

Here are some of the most common terms used by Romans to describe regions that are now part of Germany:

* Germania: This was a general term used for the lands east of the Rhine inhabited by Germanic tribes. It wasn't a precise geographical boundary.

* Germania Magna: This term was used to refer to the entire region inhabited by Germanic tribes, including areas that are now in Germany, Austria, the Netherlands, and parts of Eastern Europe.

* Germania Inferior: This referred to the lower regions of Germania, roughly corresponding to the modern Netherlands and parts of northwestern Germany.

* Germania Superior: This referred to the upper regions of Germania, roughly corresponding to parts of southwestern Germany, Switzerland, and Alsace-Lorraine.

* Various tribal names: The Romans also used the names of specific Germanic tribes to refer to their territories, like the Suebi, Chatti, Alemanni, and Franci.

It's important to note that these names were not precise or static. The borders of these regions shifted over time, and the Romans didn't always use the same terms to refer to the same areas.

So, there isn't one single "old Roman name" for Germany, but rather a variety of terms that were used to refer to the region and its inhabitants.
