Destiny sometimes also called fate (from Latin fatum 'decree prediction destiny fate') is a predetermined course of events. It may be conceived as a predetermined future whether in general or of an individual. Although often used interchangeably the words fate and destiny have distinct connotations. Distinguished from fate and destiny fortune can refer to chance or luck as in fortunate or to an event or set of events positively or negatively affecting someone or a group or in an idiom to tell someone's fortune or simply the result of chance and events. In Hellenistic civilization the chaotic and unforeseeable turns of chance gave increasing prominence to a previously less notable goddess Tyche (literally "Luck") who embodied the good fortune of a city and all whose lives depended on its security and prosperity two good qualities of life that appeared to be out of human reach. The Roman image of Fortuna with the wheel she blindly turned was retained by Christian writers including Boethius revived strongly in the Renaissance and survives in some forms today.
