DCCCLX

DCCCLX is a Roman numeral that stands for the number eight hundred sixty. The form is built from the symbols D (500), CCC (300) and LX (60). In the classic order of Roman numerals, the symbols are written in descending value from left to right, so DCCCLX represents 860 exactly.

The numeral has appeared in a variety of historical contexts. It is commonly found in medieval manuscripts, legal charters, and chroniclers’ annals where years were recorded in Roman form. In the twelfth‑century Annals of Fulda, for example, the year 860 is written as "MCMXC" in an alternate form, whereas some later Germanic documents use DCCCLX to denote that year. Monuments and inscriptions from the Early Middle Ages also employ Roman numerals; the year 860 may be seen carved on stone or metalwork in European churches or civic buildings.

Although the Roman numeral system fell out of everyday use in Western Europe after the medieval period, the form DCCCLX still survives in specialized contexts. It continues to appear in numbering chapters of certain books, the captions of classical literature, and in modern contexts where a stylized Roman numeral is desired for decorative or formal purposes, such as on commemorative medals or in the numbering of monarchs and popes.

In summary, DCCCLX is the Roman representation of 860 and has served as a conventional way of denoting that number in historical, legal, and commemorative contexts across centuries.
