Yocasta is a feminine given name of Greek origin, derived from the ancient Greek name Iokaste. It is believed to have originated from the word "iokas," meaning "violet flower." The name gained historical significance through its association with the tragic figure of Jocasta in Greek mythology.

In Greek mythology, Jocasta was the wife of King Laius of Thebes and the mother of Oedipus. The story of Oedipus and Jocasta is a central theme in Sophocles' tragic play "Oedipus Rex," which was likely written around 429 BCE. The play depicts the incestuous relationship between Oedipus and his mother, Jocasta, as a result of a prophecy and a series of unfortunate events.

One of the earliest recorded instances of the name Yocasta can be found in the works of ancient Greek authors, such as Sophocles and Euripides, who wrote their plays in the 5th century BCE. The name has been carried through various literary works, including translations and adaptations of the Oedipus myth throughout the centuries.

During the Renaissance period, the name Yocasta appeared in literary works by prominent writers. For example, Giovanni Boccaccio's "De Mulieribus Claris" (On Famous Women), written in the 14th century, featured Jocasta as one of the notable women from antiquity.

In the 16th century, the Italian playwright Lodovico Dolce wrote a tragedy titled "Giocasta," which retold the story of Jocasta and Oedipus. The play was later translated into English by William Warner in 1590.
