The strange rodent you saw in the river is a nutria, a Coypu, sort of beaver who don't make dams, though. They are not native, but were once breeded for their fur. Fortunately, nobody now wants fur coat, so they are free in nature.

Roman numerals: XII = twelfth century (10+2); XIV= fourteenth Century (10+5-1) and XV = fifteenth century (10+5)

Thanks yes takes me back to school days. Funnily I learnt in Madrid that on many clocks they used IIII instead of IV for 4

@@annsspace2600 In Madrid, they are actually right. Ancient Romans generally wrote IIII to mean 4. If you go by the Coloseum and walk around it, and you'll easily find gate number IIII. For some reason, at a later time notation changed and 4 became IV (5-1). Both notations are still in use and considered as valid.
Something that is not ofter found in school books:
X represents 2 crossed arms, so that there are 10 fingers overall;
V represents a hand, so that there are 5 fingers overall.
C simply means "Centum" (Cento in Italian, 1 hundred in English)
M means "Milia" (Mille in Italian, one thousand).
D means 500, but I don't know why.
They also had a complicated way to represent fractions of unit, not so different from Imperial System.
