A cross is a geometrical figure consisting of two lines or bars perpendicular to each other, dividing one or two of the lines in half. The lines usually run vertically and horizontally; if they run obliquely, the design is technically termed a saltire, although the arms of a saltire need not meet at right angles.

The cross is one of the most ancient human symbols, and is used by many religions, such as Christianity. It is frequently a representation of the division of the world into four elements (Chevalier, 1997) or cardinal points, or alternately as the union of the concepts of divinity, the vertical line, and the world, the horizontal line (Koch, 1955).

The word cross comes ultimately from Latin crux, a Roman torture device used for crucifixion, via Old Irish cros. The word was introduced to English in the 10th century as the term for the instrument of the torturous execution of Jesus as described in the New Testament, gradually replacing the earlier word rood.

It is not known when the first cross image was made; after circles, crosses are one of the first symbols drawn by children of all cultures. There are many cross-shaped incisions in European cult caves, dating back to the earliest stages of human cultural development in the stone age. Like other symbols from this period, their use continued in the Celtic and Germanic cultures in Europe. For example, celtic coins minted many centuries before the Christian era may have an entire side showing this type of cross, sometimes with the cardinal points marked by concave depressions in the same style as in stone age carvings. Other coins may be showing the cross held by a rider on a horse and springing a fern leaf, sometimes identified as a Tree of Life symbol.

Charles is a masculine given name, the English and French form of a Germanic name first recorded in the Anglo-Saxon period as Cearl or Ceorl, as the name of king Cearl of Mercia. The corresponding Old Norse form is Carl, the German form is Karl. The name was notably borne by Charlemagne (Charles the Great), and was at the time latinized as Karolus (as in Vita Karoli Magni), later also as Carolus.

The name's etymology is a Common Germanic noun *karlaz meaning "free man", which survives in English as churl (< Old English ċeorl), which developed its deprecating sense in the Middle English period. In the form Charles, the initial spelling ch- corresponds to the palatalization of the Latin group ca- in Central French and the final -s to the former subject case of masculine words in Old French (< Latin -us).

The name is atypical for Germanic names as it is not composed of two elements, but simply a noun meaning "(free) man". This meaning of ceorl contrasts with eorl (Old Norse jarl) "nobleman" on one hand and with þeow (Old Norse þræll) "bondsman, slave" on the other. As such it would not seem a likely candidate for the name of a Germanic king, but it is attested as such with Cearl of Mercia (fl. 620), the first Mercian king mentioned by Bede in his Historia ecclesiastica gentis Anglorum. It is a peculiarity of the Anglo-Saxon royal names that many of the rulers of the earliest period (6th to 7th centuries) have monothematic (simplex) names, while the standard dithematic (compounded) names become almost universial from the 8th century. Compare the name of king Mul of Kent (7th century) which simply translates to "mule".

Kurt Donald Cobain (February 20, 1967 – April 5, 1994) was an American singer-songwriter, musician and artist, best known as the lead singer and guitarist of the grunge band Nirvana. Cobain formed Nirvana with Krist Novoselic in Aberdeen, Washington in 1985 and established it as part of the Seattle music scene, having its debut album Bleach released on the independent record label Sub Pop in 1989.

After signing with major label DGC Records, the band found breakthrough success with "Smells Like Teen Spirit" from its second album Nevermind (1991). Following the success of Nevermind, Nirvana was labeled "the flagship band" of Generation X, and Cobain hailed as "the spokesman of a generation". Cobain, however, was often uncomfortable and frustrated, believing his message and artistic vision to have been misinterpreted by the public, with his personal issues often subject to media attention. He challenged Nirvana's audience with its final studio album In Utero (1993).

During the last years of his life, Cobain struggled with heroin addiction, illness and depression. He also had difficulty coping with his fame and public image, and the professional and lifelong personal pressures surrounding himself and his wife, musician Courtney Love. On April 8, 1994, Cobain was found dead at his home in Seattle, the victim of what was officially ruled a suicide by a self-inflicted shotgun wound to the head. The circumstances of his death at age 27 have become a topic of public fascination and debate. Since their debut, Nirvana, with Cobain as a songwriter, has sold over 25 million albums in the U.S. alone, and over 50 million worldwide.
