Juts to note - I assumed circles were dots and the longer ones were dashes, for the morse code.
Inverting that gives AESSOGGYÆI
In my head I read it in a Scottish accent as "Aye, it's soggy eh ?" haha
Aside from that, some basic binary comparisons don't turn up much (to me anyway)
If the message is taken to be 10 1 111 111 000 001 001 0100 1010 11 in binary, that gives 2 1770114103 decimal and inverted gives 10007661150 if you treat each group as its own distinct number.
Maybe where the dot or the Θ (theta symbol ?) is could be a decimal point ?
Also, in the image at 4 o'clock there looks to be a perpendicular dash across the spiral.
