In Greek mythology, Bia (Ancient Greek: Βία, English translation: "Force") was the personification of force, daughter of Pallas and Styx, and sister of Nike, Kratos, and Zelus.

She and her siblings were constant companions of Zeus. They achieved this honour after supporting Zeus in the war against the Titans along with their mother. Bia is one of the characters named in the Greek tragedy Prometheus Bound, written by Aeschylus, where Hephaestus is compelled by the gods to bind Prometheus after he was caught stealing fire and offering the gift to mortals.

BIA or Bia may refer to:

The term "mythology" can refer either to the study of myths (e.g., comparative mythology), or to a body or collection of myths (a mythos, e.g., Inca mythology). In folkloristics, a myth is a sacred narrative usually explaining how the world or humankind came to be in its present form, although, in a very broad sense, the word can refer to any traditional story. Myths typically involve supernatural characters and are endorsed by rulers or priests. They may arise as overelaborated accounts of historical events, as allegory for or personification of natural phenomena, or as an explanation of ritual. They are transmitted to convey religious or idealized experience, to establish behavioral models, and to teach.

Early rival classifications of Greek mythos by Euhemerus, Plato's Phaedrus, and Sallustius were developed by the neoplatonists and revived by Renaissance mythographers as in the Theologia mythologica (1532). Nineteenth-century comparative mythology reinterpreted myth as evolution toward science (E. B. Tylor), "disease of language" (Max Müller), or misinterpretation of magical ritual (James Frazer). Later interpretations rejected opposition between myth and science, such as Jungian archetypes, Joseph Campbell's "metaphor of spiritual potentiality", or Lévi-Strauss's fixed mental architecture. Tension between Campbell's comparative search for monomyth or Ur-myth and anthropological mythologists' skepticism of universal origin has marked the 20th century. Further, modern mythopoeia such as fantasy novels, manga, and urban legend, with many competing artificial mythoi acknowledged as fiction, supports the idea of myth as ongoing social practice.

Christina María Aguilera (born December 18, 1980) is an American recording artist and actress. Aguilera first appeared on national television in 1990 as a contestant on the Star Search program, and went on to star in Disney Channel's television series The Mickey Mouse Club from 1993 to 1994. Aguilera signed to RCA Records after recording "Reflection", the theme song for the animated film Mulan (1998).

In 1999, Aguilera came to prominence following her debut album Christina Aguilera, which was a commercial success spawning three number one singles on the Billboard Hot 100—"Genie in a Bottle", "What a Girl Wants", and "Come On Over Baby (All I Want Is You)." Her sophomore and her debut Latin-pop album, Mi Reflejo (2000), a Christmas third studio album, My Kind of Christmas (2000), and several collaborations followed which garnered Aguilera worldwide success, though she was displeased with her lack of input in her music and image. After parting from her management, Aguilera took creative control over her fourth studio album, Stripped (2002). The album's second single, "Beautiful", was a commercial success and helped the album's commercial performance amidst controversy over Aguilera's image. Aguilera followed up Stripped with the soul, jazz and blues inspired, Back to Basics (2006), released to positive critical acclaim. The album produced three singles "Ain't No Other Man", "Hurt" and "Candyman". Four years later Aguilera released her sixth studio album, Bionic (2010), which incorporated aspects of R&B, electropop, and synthpop and was met with mixed reviews and low sales. Aguilera's seventh studio album is set to be released in 2012.
