Culture generally refers to the patterns of human activity, and the symbolic structures that give such activities significance and importance. Cultures can be "understood as systems of symbols and meanings that even their creators contest, that lack fixed boundaries, that are constantly in flux, and that interact and compete with one another". Culture can be defined as all the ways of life: including arts, beliefs, and institutions of a population that are passed down from generation to generation. Culture has been called "the way of life for an entire society". As such, it includes codes of manners, dress, language, religion, rituals, and norms of behavior, such as law and morality and systems of belief as well as art.
Today the Greeks call themselves Hellenes (Έλληνες), though they have been known by a number of different names throughout history. The soldiers that fell at Thermopylae did so as Hellenes. During the time of Jesus, the term shifted and any person of non-Jewish faith was called Hellene. By late Antiquity, the Greeks referred to themselves as Romaioi, i.e. Romans. Western Europeans used the term Greeks and the Persians and the Turks used the term Yunans, i.e. Ionians. An interesting and unique form is kept in Georgian. In ancient times, Georgians (Colchians and Iberians) called Greeks ბერძენი berdzeni. This form derives from the Georgian word ბრძენი brdzeni – wise. According to Georgian historians, the name is connected with the notion that philosophy was born in Greece. Modern Georgians still call Greeks ბერძენი berdzeni and Greece საბერძნეთი saberdznet'i, 'Greeks' land' or literally 'land of the wise'. The onset of every historical era was accompanied by a new name, either entirely new or formerly old and forgotten, extracted from tradition or borrowed from foreigners. Each of them was significant in its own time, and all can be used interchangeably, which means that the Greeks are a polyonymous people.
A vertical Tibetan prayer flag in the Zanskar region of northern India. The vertical style, called darchor, is less common than the horizontal style, called lungta. Horizontal prayer flags are squares connected at the top edges with a long thread. The vertical prayer flags are usually single squares or groups of squares sewn on poles which are planted in the ground or on rooftops. Unique to Tibetan Buddhism, these flags are panels or rectangles of colourful cloth strung along mountain ridges and peaks in the Himalayas to bless the surrounding countryside. Prayer flags are believed to have originated with the original Bön religion which pre-dated Buddhism in Tibet.
