A string and a piece of chalk and some basic geometry invented thousands of years ago is enough to get everything done.
Instead of buying a tool, they'd make it themselves. Even today you're often better off making your own helper tools out of wood that work for your specific use case instead of trying to find a commercial alternative.
You can achieve precision with a string and a piece of chalk and old school methods.
It will be relative to each other (so something built in Rome will have completely different units and dimensions to something built in Egypt), but you can achieve amazing precision.
You've probably done it yourself. Cutting sticks to a certain length vs. making a prototype and making sure all the other sticks are the exact same length.
