Presumably a taut piece of thread would be enough. The use of thread in architecture and for plumb-lines goes back a ways.

In railway alignment metal eyes are used, which are just sheets of metal with a hole in them. When placed along the track if you can see through all the holes the track is correctly aligned.

Both are low-tech solutions that can produce relatively accurate straight lines without a ruler.

Apparently the first type of ruler dates back to ancient Egypt, it was called a 'Cubit rod' 44228 it could date back further though but with the massive structures the Egyptians were building, a straight piece of wood seems like a pretty easy thing to think of.2013-02-08 01:13:00

I thought this was going to be some deep religious debate over how God was made. Then I realised it wasn't that kind of 'ruler' 2013-02-11 14:45:00

I was taught in school (probably erroneously), that historically the measurement of "1 Foot" was taken from the ruling Monarch, meaning that each time a new Monarch was coronated, they would need to recalculate the measures.
That's why it's called the "imperial" system.
