The list of twelve Horae representing the twelve hours of the day is recorded only in Late Antiquity, by Nonnus. The first and twelfth of the Horae were added to the original set of ten:

Auge (first light)
Anatole (sunrise)]
Mousike (morning hour of music and study)
Gymnastike (morning hour of exercise)
Nymphe (morning hour of ablutions)
Mesembria (noon)
Sponde (libations poured after lunch)
Elete (prayer)
Akte (eating and pleasure)
Hesperis (start of evening)
Dysis (sunset)
Arktos (night sky)

Middle Ages
Medieval astronomers such as al-Biruni and Sacrobosco,   divided the hour into 60 minutes, each of 60 seconds; this derives from Babylonian astronomy, where the corresponding terms denoted the time required for the Suns apparent motion through the ecliptic to describe one minute or second of arc, respectively. In present terms, the Babylonian degree of time was thus four minutes long, the "minute" of time was thus four seconds long and the "second" 1/15 of a second.) In medieval Europe, the Roman hours continued to be marked on sundials but the more important units of time were the canonical hours of the Orthodox and Catholic Church. During daylight, these followed the pattern set by the three-hour bells of the Roman markets, which were succeeded by the bells of local churches. They rang prime at about 6 am, terce at about 9 am, sext at noon, nones at about 3 pm, and vespers at either 6 pm or sunset. Matins and lauds precede these irregularly in the morning hours; compline follows them irregularly before sleep; and the midnight office follows that.
A dermatofibroma, or benign fibrous histiocytomas, is a benign nodule in the skin, typically on the legs, elbows and chest of an adult. It is usually painless.Its size usually ranges from 0.2cm to 2cm, and have been reported to be larger. It typically results from mild trauma such as an insect bite. Risk factors for developing multiple dermatofibromas include lupus, HIV, blood cancer and some medicines that weaken immunity.It is usually diagnosed by its appearance, but a biopsy may be required. Other bumps such as granular cell tumor, melanoma, clear cell acanthoma and dermatofibrosis lenticularis disseminata may look similar. Reassurance is generally given and usually no treatment is needed. It can remain unchanged for years, but can resolve spontaneously. Signs and symptoms
Dermatofibromas are hard solitary slow-growing papules (rounded bumps) that may appear in a variety of colours, usually brownish to tan; they are often elevated or pedunculated. A dermatofibroma is associated with the dimple sign; by applying lateral pressure, there is a central depression of the dermatofibroma. Although typical dermatofibromas cause little or no discomfort, itching and tenderness can occur. Dermatofibromas can be found anywhere on the body, but most often they are found on the legs and arms. They occur most often in women; the male to female ratio is about 1:4. The age group in which they most commonly occur is 20 to 45 years. Some physicians and researchers believe dermatofibromas form as a reaction to previous injuries such as insect bites or thorn pricks.
