I saw this on FB by a Spanish group. The right person maybe hasn't seen my question on it, but what exactly is it? It is in a group of photos with a groma, so is perhaps a portable level?

Richard,I don't no what it is, but you suggestion may be right. How is you groma btw? My next project wil be the waterlevel as discribed by vitruvius and on a drawing in Dilkes book.

Quote:Leveling the Ground: Water Levels and the Inclinometer
For much of their work, the Roman surveyors had to prepare flat surfaces or maintain an incline. For leveling ground, especially where it needed to be flat, the Roman surveyors used a rudimentary spirit level, which consisted of an elongated basin with a mark at either end to signify the level. There is little literary or archaeological evidence that they used this, but it was used by the Egyptians and the Greeks making it very likely that the Roman surveyors used it.
Thanks, I think that fits it. This fellow is with the Spanish group Hispana Romana and has a large number of impressive reconstructions that have taken him years to research. The group is on Facebook but I'm trying to talk him into sharing here.
