Problem: Hippolytus of Rome (170 - 235 AD) was one of the most important 3rd-century theologians in the Christian Church in Rome, where he was probably born. Photios I of Constantinople describes him in his Bibliotheca (cod. 121) as a disciple of Irenaeus, who was said to be a disciple of Polycarp, and from the context of this passage it is supposed that he suggested that Hippolytus so styled himself. However, this assertion is doubtful.

The facts of his life as well as his writing were soon forgotten in the West, perhaps by reason of his criticism of the bishops of Rome and because he wrote in Greek. Pope Damasus I dedicated to him one of his famous epigrams, making him, however, a priest of the Novatianist schism, a view later accepted by Prudentius in the 5th century in his "Passion of St Hippolytus". In the Passionals of the 7th and 8th centuries he is represented as a soldier converted by Saint Lawrence, a legend that long survived in the Roman Breviary. He was also confused with a martyr of the same name who was buried in Portus, of which city he was believed to have been a bishop, who was put to death by drowning in a deep well.  According to Prudentius' account, Hippolytus was dragged to death by wild horses, a striking parallel to the story of the mythological Hippolytus, who was dragged to death by wild horses at Athens. He described the subterranean tomb of the saint and states that he saw there a picture representing Hippolytus' execution. He also confirms August 13 as the date on which a Hippolytus was celebrated but this again refers to the convert of Lawrence, as preserved in the Menaion of the Eastern Orthodox Church.  The latter account led to Hippolytus being considered the patron saint of horses. During the Middle Ages, sick horses were brought to St Ippolyts, Hertfordshire, England, where a church is dedicated to him.

When was Hippolytus a leader?

Question:
"Vogue" is a song by American singer Madonna from her second soundtrack album I'm Breathless (1990). It was released as the first single from the album on March 27, 1990, by Sire Records. Madonna was inspired by vogue dancers and choreographers Jose Gutierez Xtravaganza and Luis Xtravaganza from the Harlem "House Ball" community, the origin of the dance form, and they introduced "Vogueing" to her at the Sound Factory club in New York City. "
The video was directed by David Fincher and shot at The Burbank Studios in Burbank, California on February 10-11, 1990. According to Lucy O'Brien in her book Madonna: Like an Icon, the video was brought together after a "huge casting call" in Los Angeles where hundreds of different sorts of dancers appeared.  Filmed in black-and-white, the video recalls the look of films and photography from The Golden Age of Hollywood with the use of artwork by the Art Deco artist Tamara de Lempicka and an Art Deco set design. Many of the scenes are recreations of photographs taken by noted photographer Horst P. Horst, including his famous Mainbocher Corset, Lisa with Turban (1940), and Carmen Face Massage (1946). Horst was reportedly "displeased" with Madonna's video because he never gave his permission for his photographs to be used and received no acknowledgement from Madonna. Some of the close-up poses recreate noted portraits of such stars as Marilyn Monroe, Veronica Lake, Greta Garbo, Marlene Dietrich, Katharine Hepburn, Judy Garland and Jean Harlow. (Additionally, several stars of this era were name-checked in the song's lyrics.) Several famous Hollywood portrait photographers whose style and works are referenced include George Hurrell, Eugene Robert Richee, Don English, Whitey Schafer, Ernest Bachrach, Scotty Welbourne, Laszlo Willinger, and Clarence Sinclair Bull.  The video features the dancers for Madonna's then-upcoming Blond Ambition Tour - Donna De Lory, Niki Harris, Luis Xtravaganza Camacho, Jose Gutierez Xtravaganza, Salim Gauwloos, Carlton Wilborn, Gabriel Trupin, Oliver Crumes and Kevin Stea. The choreography was set by "Punk Ballerina" Karole Armitage. The video premiered worldwide on MTV on March 29, 1990, and it also premiered on BET on November 22 that same year, making itthe first video by Madonna to air on an African-American channel.  There are two versions of the video, the regularly aired television music video, and the 12-inch remix, which is the extended version over three minutes longer.
