The scriptwriter is taking poetic license when Pierre tells Natalie that the ancient Greeks called the planet Venus - Callisto. When, in fact, the Greeks referred to Venus as Aphrodite. Callisto was a river nymph and not the Greek goddess of love and being a Nymph could not be the name of a God or Goddess which only were used to name planets, not the satellites/moons that accompanied them. Furthermore, Callisto was discovered not in ancient Greek times but in 1610 by Galileo Galilei because mankind had recently discovered the technology of telescopes.
Henri Désiré Landru (12 April, 1869 - 25 February, 1922) was a French serial killer, nicknamed the Bluebeard of Gambais. He was married with a 25-year-old son. He murdered at least 10 women and one male --- his first victim's teenage son.
The true number of Landru's victims is suspected to be higher. The police eventually concluded that Landru had met or been in romantic correspondence with 283 women during the First World War; 72 were never traced. Landru's trial in November 1921 at Versailles was attended by leading French celebrities, including the novelist, Colette, and the actor and singer, Maurice Chevalier. Landru was found guilty by a majority verdict of 11 murders, and sentenced to death. He was executed by guillotine on February 25, 1922.
