As you probably noticed I'm using AUC system, which basically stands for 'ab urbe condita' - 'from the founding of the city'. This system is based on the year of Founding of Rome - 753 BC. I also added years in traditional dating system (in brackets) to avoid confusion. I chose AUC system because of inability to implement reverse years (BC) in Crusader Kings and because AUC mostly fits this time period.

With 1363 AUC (610 AD) the game ends. In 610 AD Emperor Heraclius of Eastern Roman Empire declared himself Basileus while renouncing Latin as administration language in Empire of the East and implementing Greek in its place. This year thus marks the end of most of Roman heritage and at some point - influences of Antiquity.

As you can see I got some fancy idea to give latin name to every bookmark. Unfortunately I managed to give proper names to only some of them, as I don't have the idea for the rest. The last bookmark is named in Greek (it's a quote from Justinian the Great after he finished Hagia Sophia), because of my insufficient knowledge of Latin I was unable to translate it (great thanks to anyone who knows Latin and could translate it for me).

*temporary name - name is temporary and will be invented in future
**temporary name - name is temporary and has to be translated to Latin

Credit goes to vikior for inventing 'Flagellum Dei' and 'Roma Victa' names.
