Janus Chess is a chess variant played on a 10×8 board.
 It features one variant chess piece, the "janus", with the combined moves of a bishop and a knight.
 The piece is named after the Roman god Janus because this god was usually depicted with two faces looking in opposite directions.
 The game starts with two januses on the board for each color.
 The janus is also known as an "archbishop", "cardinal", or "princess", which varies based on the game it is used in.
 "Janus Chess" was invented in 1978 by Werner Schöndorf from Bildstock, Germany.
Graciela Amaya de García (11 January 1895-11 October 1995) was a Central American feminist and labor organizer.
 Born in El Salvador and trained as a teacher, she moved to Honduras at the age of twenty.
 Joining the socialist movement, she became a party operative, founding trade unions to resist the labor practices of the industrialists operating in the country.
 She formed the first feminist organization of Honduras, the Society of Feminist Culture, in 1923 and organized night schools for working women to teach them about their rights.
 Expelled from Honduras for leading demonstrations against the government in 1944, she fled home to El Salvador but remained only a few months because a coup d'etat brought in a dictatorship.
 Relocating to Guatemala, García continued with her activities organizing labor and educating working class people, until she was expelled by the president in 1946.
 Moving to Mexico, she worked for the Secretariate of Education and wrote articles in support of leftist politics and women.

Janus was a feminist science fiction fanzine edited by Janice Bogstad and Jeanne Gomoll in Madison, Wisconsin, and closely associated with that city's science fiction convention, WisCon (Several early WisCon program books doubled as special issues of "Janus".)
 It was repeatedly nominated for the Hugo Award for Best Fanzine (1978, 1979 and 1980); this led to accusations that if "Janus" had not been feminist, it wouldn't have been nominated.
 Eighteen issues were published under this name from 1975–1980; it was succeeded by "Aurora SF" ("Aurora Speculative Feminism").
