Feriæ

In Roman law. Holidays; generally speaking, days or seasons during which free-born Romans suspended their political transactions and their lawsuits, and during which slaves enjoyed a cessation from labor, all feriœ were thus dies nefasti. All feriœ were divided into two classes,—"feriœ publicœ" and "feriœ p rivat œ." The latter were only observed by single families or individuals, in commemoration of some particular event which had been of importance to them or their ancestors. Smith, Diet Antiq.
