The horizon
A wavy blue line on a map usually indicates water. I could indicate a river, canal, or any type of waterway.
Sort of. There is a Druidic symbol for truth, although, like many other symbols, it has other meanings. Since Druids and Celts are associated with Ireland, it's probably a good bet the symbols would be the same (or at least quite similar). Although some pictures of the symbol only show the three lines, for a tattoo, you might want to add the three circles on top of each line. Now to describe this symbol: First, it's usually enclosed by three circles. The number 3 is very important in Celtic culture. Second, the middle line is centered and straight. The lines to the left and right flare out from the middle line, but also appear straight. At the top of each line is a small circle filled in with black. If you can find a magazine with Celtic designs, look for the symbol known as "Awen".
A national boundry is a thick black line
A horizontal line creates calmness, order. A diagonal line implies conflict, and a vertical line usually creates stability.
Instead of a mechanical looking line, a line with variation will go from thin to wide, and/or light to dark, and is usually more organic looking.
