Eros is the popular name for the wingèd archer in the centre of Piccadilly Circus. A memorial to the 7th Earl of Shaftesbury, it is the work of Sir Alfred Gilbert (1854–1934) and was unveiled in 1893.
There has never been an official name for the wingèd figure specifically. The entire installation was originally called the Shaftesbury Memorial Fountain, and later became known simply as the Shaftesbury Memorial when the fountain was decommissioned.
According to Wikipedia, “Although the statue is generally known as Eros, it was created as an image of his brother, Anteros.” This is nonsense (and the sole supporting citation is the notoriously fallible QI Book of General Ignorance). It’s true that Alfred Gilbert himself made this claim at one point, but it was one of various conflicting statements that the sculptor made about the inspiration for the statue some years after the work had been completed and installed. Gilbert seems to have come up with the Anteros afterthought as one of his many attempts to justify his work in the face of prolonged (at times rabid) criticism from late-Victorian moralists. The same motive applied to Gilbert’s retrospective suggestion that the statue represented ‘the angel of Christian charity’.
At the time the work was installed, no one was in much doubt that the figure was Eros rather than Anteros or any other alternative character, and the same view is held by the overwhelming majority of knowledgeable authorities today. The City of Westminster always calls the statue Eros or the Eros monument.
