Runes? Roman? Ogham!

Recently a series of lines, jumbled together in their medium, were uncovered and examined by me. Pondering their meaning, I tried to decipher them as runes, but they weren't clear enough. Thinking perhaps the roman style script (all were straight lines) I reexamined them, but there seemed to be no common axis. In fact, the lines looked like vertical and diagonal hatches on a base line which was curved into a spiral.

Going on this hunch, I investigated Ogham, and after finding a very cool website:

I was able to decipher the runes...
leaving out the scholarship, they translated to:
blocc th ng shots.

Hmm. Interesting bruise after war practice tonight....:)
