Tyche was worshipped in Rome under the name of Fortuna, and held a position of much greater importance among the Romans than the Greeks.
In later times Fortuna is never represented either winged or standing on a ball; she merely bears the cornucopia. It is evident, therefore, that she had come to be regarded as the goddess of good luck only, who brings blessings to man, and not, as with the Greeks, as the personification of the fluctuations of fortune.
In addition to Fortuna, the Romans worshipped Felicitas as the giver of positive good fortune.
ANANKE (Necessitas).
As Ananke, Tyche assumes quite another character, and becomes the embodiment of those immutable laws of nature, by which certain causes produce certain inevitable results.
In a statue of this divinity at Athens she was represented with hands of bronze, and surrounded with nails and hammers. The hands of bronze probably indicated the irresistible power of the inevitable, and the hammer and chains the fetters which she forged for man.
Ananke was worshipped in Rome under the name of Necessitas.
KER.
In addition to the Moiræ, who presided over the life of mortals, there was another divinity, called Ker, appointed for each human being at the moment of his birth. The Ker belonging to an individual was believed to develop with his growth, either for good or evil; and when the ultimate fate of a mortal was about to be decided, his Ker was weighed in the balance, and, according to the preponderance of its worth or worthlessness, life or death was awarded to the human being in question. It becomes evident, therefore, that according to the belief of the early Greeks, each individual had it in his power, to a certain extent, to shorten or prolong his own existence.
