I have been working on Chapter 4 for about 3 weeks and still have not been able to make any head way. Any more hints would be great. I have plugged in numerous sequences of numbers and non of them are correct. Please help!!!

First turn the roman to arabic numbers. Then look at the numerals: the first numeral from line one and the first numeral from line three will give you the first numeral of the solution (simply use the circle to find the middle).
