I looked up some symbol ciphers and found this:

Google Symbols

This looks interesting, similar symbols.

The Ciphers of the Monks

Wikipedia

Our “Scroll” seems to be a type of monk cipher.

The system uses a vertical straight line as its main symbol. This symbol is essentially an axis that divides the two-dimensional plane into four quadrants.

Here is a diagram of how each symbol is created:

Each symbol on our cipher represents a number.

Let’s take our first symbol:

First

This comprises of 70:

70

And 2:

2

So our first symbol represents the number 72. Carry this on for all of the symbols.

70 + 2 = 72

80 + 4 = 84

60 + 6 = 66

100 + 3 + 20 = 123

70 + 7 = 77

40 + 8 = 48

70 + 8 = 78

7 + 100 = 107

5 + 10 + 100 = 115

90 + 5 = 95

100 + 7 = 107

70 + 8 = 78

50 + 1 = 51

10 + 9 + 100 = 119

30 + 3 = 33

5 + 20 + 100 = 125

= 72 84 66 123 77 48 78 107 115 95 107 78 51 119 33 125

The outcome looks like a string of decimals. This has to be ASCII so let’s input this on an online converter:
