The lower part may be Roman, as I am inclined to believe;

The name of the place is et-Tabgha, which recent authorities 
believe to be a corruption of the Greek Heptapegon (‘‘ seven 
pool to work a water-mill or water mills in a totally different direc- 
tion from that of the existing water-course. There is, indeed, 
evidence that the distance to which this water was conducted 
was different at different periods. I believe that now, whatever 
may have once been the case, there is no connection between 
the pool and the lake. In October, 1912 the whole surface was 
overgrown with floating grasses of great size. 
At 11 a.m. on October 22nd, the air-temperature imme- 
diately above the surface of the water in the pool being 30°C., 
the water itself at the surface had a temperature of 27°C. At 
the same time that of the existing mill-race, at the point at 
which it issued from the ground, was 25°C., all being in the 
shade. Bubbles of gas were observed ascending almost con- 
tinuously from the bottom of the pool at this time, but no 
smell could be detected.’’ 
The specific gravity of the water is 1:00295 (55) or
