CDLII

CDLII is the Roman numeral for 452. The notation uses subtractive and additive principles, with CD representing 400, L representing 50, and II representing 2. Therefore CDLII equals 452.

In the Roman numeral system, symbols C(100), D(500), L(50), and I(1) are combined to form numbers. When a smaller value precedes a larger one, it is subtracted (CD = 400). Otherwise values are added (L + II = 52).

Historically, the year 452 CE was marked by Attila the Hun's invasion of Italy and the subsequent diplomacy with Pope Leo I, which is thought to have contributed to halting the Hun campaign. In modern usage, CDLII can appear on clocks, monuments, citations, or as a stylistic element in outlines or enumerations where Roman numerals are preferred. It serves as an example of subtractive notation and is used in various fields requiring traditional numbering.
