Antaeus (, Antaîos,  "Opponent"; ) was a figure in Greek and Berber mythology. In Greek sources, he was the half-giant son of Poseidon and Gaia. His wife was the goddess Tinge, and he had a daughter named Alceis or Barce. He was famed for his loss to Hercules during that demigod's 12 Labors.

Anti is the eighth studio album by Barbadian recording artist Rihanna, released on January 28, 2016, through Westbury Road and Roc Nation. The singer began planning the record in 2014, at which time she left her previous label Def Jam and joined Roc Nation. Work continued into 2015, during which she released three singles, including the internationally acclaimed "FourFiveSeconds"; they were ultimately removed from the final track listing. The record was made available for free digital download on January 28 through Tidal and was released to online music stores for paid purchase on January 29. Anti is scheduled to be released to physical retailers on February 5.
