input: Eratosthenes was described by the Suda Lexicon as a Pentathlos (Pentathlos) which can be translated as "All-Rounder", for he was skilled in a variety of things: He was a true polymath. He was nicknamed Beta because he was great at many things and tried to get his hands on every bit of information but never achieved the highest rank in anything; Strabo accounts Eratosthenes as a mathematician among geographers and a geographer among mathematicians.  Eusebius of Caesarea in his Preparatio Evangelica includes a brief chapter of three sentences on celestial distances (Book XV, Chapter 53). He states simply that Eratosthenes found the distance to the Sun to be "stadion muriadas tetrakosias kai oktokismurias" (literally "of stadia myriads 400 and 80,000") and the distance to the Moon to be 780,000 stadia. The expression for the distance to the Sun has been translated either as 4,080,000 stadia (1903 translation by E. H. Gifford), or as 804,000,000 stadia (edition of Edouard des Places, dated 1974-1991). The meaning depends on whether Eusebius meant 400 myriad plus 80,000 or "400 and 80,000" myriad. With a stade of 185 m, 804,000,000 stadia is 149,000,000 km, approximately the distance from the Earth to the Sun.  Eratosthenes also calculated the Sun's diameter. According to Macrobious, Eratosthenes made the diameter of the Sun to be about 27 times that of the Earth. The actual figure is approximately 109 times.  During his time at the Library of Alexandria, Eratosthenes devised a calendar using his predictions about the ecliptic of the Earth. He calculated that there are 365 days in a year and that every fourth year there would be 366 days.  He was also very proud of his solution for Doubling the Cube. His motivation was that he wanted to produce catapults. Eratosthenes constructed a mechanical line drawing device to calculate the cube, called the mesolabio. He dedicated his solution to King Ptolemy, presenting a model in bronze with it a letter and an epigram. Archimedes was Eratosthenes' friend and he, too, worked on the war instrument with mathematics. Archimedes dedicated his book The Method to Eratosthenes, knowing his love for learning and mathematics.

Answer this question "Did he map the moon?"
output: the distance to the Moon to be 780,000 stadia.

Question: RuPaul's Drag Race is an American reality competition television series produced by World of Wonder for Logo TV and, beginning with the ninth season, VH1. The show documents RuPaul in the search for "America's next drag superstar." RuPaul plays the role of host, mentor, and head judge for this series, as contestants are given different challenges each week. RuPaul's Drag Race employs a panel of judges, including RuPaul, Michelle Visage, Ross Mathews, Carson Kressley, and a host of other guest judges, who critique contestants' progress throughout the competition.

Beginning with the seventh season, Michelle Visage, Ross Mathews and Carson Kressley are the staple judges alongside RuPaul. Visage joined the show at the start of season 3, while Mathews and Kressley joined at the start of season 7, and each joins RuPaul and Visage on alternate episodes. Past fixtures on the panel include Merle Ginsberg, who was a regular judge in the first two seasons, and Santino Rice, who held his position from the first season until the conclusion of the sixth. Until season 8, Rice was the only person, apart from RuPaul, to take part in every season of the show, serving as a main judge for seasons one through six, and all stars 1, and guest judging for season seven. In certain instances, Rice was absent and replacement judging has been provided by make-up artist Billy Brasfield (better known as Billy B), Mike Ruiz, Jeffrey Moran (Absolut Vodka marketing executive), or Lucian Piane. However, due to Brasfield's numerous appearances in seasons three and four, including appearing in the Reunited episodes both seasons, Rice and Billy B are considered to have been alternates for the same seat at the judges table throughout the two seasons.  Prior to the grande finale, the three main judges are joined by two celebrity guest judges each week. Guest judges have included Paula Abdul, Pamela Anderson, Eve, Ariana Grande, Neil Patrick Harris, Kathy Griffin, Debbie Harry, Khloe Kardashian, La Toya Jackson, Adam Lambert, Demi Lovato, Bob Mackie, Rose McGowan, Olivia Newton-John, Rebecca Romijn, Gigi Hadid, Sharon Osbourne, Dan Savage, John Waters, Michelle Williams, Candis Cayne, Martha Wash, Natalie Cole, Dita Von Teese, Niecy Nash, Debbie Reynolds, Vanessa Williams, Wilmer Valderrama, The Pointer Sisters, Trina, Leah Remini, The B-52's, Kesha and Lady Gaga.  The judges each provide their opinion on the contestants' performances in the main challenge and on the runway before RuPaul announces which queen is the episode's winner and which two had the weakest performances. The day before judging, the contestants are all provided with a song to which they must learn the lyrics. The contestants deemed as being the bottom two must "lip sync for their lives" to the song in a final attempt to impress RuPaul. After the lip sync, RuPaul alone decides who stays and who leaves. RuPaul describes the qualities the contestants must have to be crowned the winner of the show as "Charisma, Uniqueness, Nerve, and Talent... These are people who have taken adversity and turned it into something that is beautiful and something powerful." The phrase "charisma, uniqueness, nerve, and talent" is used repeatedly on the show, the acronym of which is CUNT. On the first All Stars season, "synergy" was added to provide an explanation behind the contestants being sorted into teams (expanding the acronym into CUNTS).

Using a quote from the above article, answer the following question: how long did he judge?
