Festivals in honor of Janus were celebrated on the first day of the new year; and one month bore the god’s name, and was considered sacred to him. It was customary for friends and relatives to exchange calls, good wishes, and gifts on the first day of this month,—a Roman custom in force to this day.

Ancient divisions of time.

Janus is not the only one among the Greek and Latin divinities whose name has been given to a part of the year or week; for in Latin the names of the days are dies Solis (Sun day), dies Lunæ (Moon day), dies Martis (Mars’ day), dies Mercurii (Mercury’s day), dies Jovis (Jove’s day), dies Veneris (Venus’ day), dies Saturni (Saturn’s day); Latin names which are still in use in legislative and judiciary acts, while in English the common nomenclature is derived from the names of the corresponding Saxon divinities.

CHAPTER XVII.
SOMNUS AND MORS.

Cave of sleep.

After leaving the joyless regions of Pluto’s realm, and following the even course of the Lethe River, the ancients fancied one reached a large cave in a remote and quiet valley. This cave was the dwelling of Somnus (or Hupnos), god of sleep, and of his twin brother Mors (or Thanatos), god of death; and both were sons of the Goddess of Night, who had once ruled the whole universe. Near the entrance of the cave, shadowy forms kept constant watch, gently shaking great bunches of poppies, and, with finger to lips, enjoining silence on all who ventured near. These forms were the genii of sleep and death, represented in art as crowned with poppies or amaranths, and sometimes holding a funeral urn or a reversed torch.

Somnus and Morpheus.

The cave was divided into chambers, each one darker and more silent than the one which preceded it. In one of the inner rooms, which was all draped with sable curtains, stood a downy couch, upon which reclined the monarch of sleep. His garments were also black, but all strewn with golden stars. He wore a crown of poppies on his head, and held a goblet full of poppy juice in his languid hand. His drowsy head was supported by Morpheus, his prime minister, who watched incessantly over his prolonged slumbers, and hindered any one from troubling his repose.
