Problem: Background: The Riddler (Edward Nigma) is a fictional supervillain appearing in American comic books published by DC Comics, commonly as an adversary of the superhero Batman. The character made his first appearance in Detective Comics #140 (October, 1948) and was created by Bill Finger and Dick Sprang. Depicted as a Gotham City criminal mastermind, the Riddler takes delight in incorporating riddles and puzzles into his plots, and leaves them as clues for the authorities and Batman to solve. The character is one of Batman's most enduring enemies and belongs to the collective of adversaries that make up Batman's rogues gallery.
Context: The Riddler makes his first true appearance in the new DC continuity relaunch, DC Rebirth, in Batman #19. An inmate of Arkham once again, he rather cooperatively assists Bane in unlocking a high tech door, allowing Bane access to confront Batman.  In the eight-part story-arc "War of Jokes and Riddles", commencing with Batman Vol. 3 #25, flashbacks to a year after the events of "Zero Year" have Batman recounting the details of a war between Riddler and Joker. He is first seen in custody at the GCPD, assisting them in solving a variety of crimes, including locating Joker's whereabouts, before stabbing a police officer to death 26 times. Blackmailing the approaching guards with details of their children and families, Riddler walks out freely before intruding into Joker's office. Riddler seemingly offers the Joker a partnership, acknowledging that if either of the two men individually kill Batman, the other will be left forever unsatisfied. However the Joker shoots Riddler in the stomach and quickly departs, Batman appearing through the window and giving chase. Left in a pool of his own blood, Riddler rose to his feet and limped out of the office, seemingly unfazed.  Edward quickly healed from the wound, carving a question marked shaped scar over the wound, before murdering Dr. Jaime Knowles. Riddler is then seen meeting with Poison Ivy, discussing the Joker's need to rid anyone who could potentially kill Batman before him. The duo are then ambushed by gunmen working for Carmine Falcone under the orders of the Joker to kill Riddler within the hour. However Poison Ivy attacks the gunmen with her vines, allowing Edward and herself to leave.  Riddler eventually formed his team, consisting on himself, Poison Ivy, Scarecrow, Deathstroke, Clayface, Killer Croc, Two-Face, Firefly, and Victor Zsasz. Waging war on Joker's team across Gotham, Riddler is responsible for poisoning Charles Brown's son, resulting in his transformation into Kite Man who joins up with Joker's team consisting of Cluemaster, Deadshot, Mad Hatter, Man-Bat, Mr. Freeze, Penguin, Solomon Grundy, and Ventriloquist. The war continues, with Riddler and Joker claiming territories across Gotham, before Riddler, who'd convinced Batman to side with him during the conflict, blackmails and interrogates Kite Man into giving up Joker's location. However Batman, after a brief fight between him, Riddler and Joker, becomes disgusted by Riddler's actions and quickly grabs a blade, breaking his one rule of No Killing in order to stab Riddler. However Joker, who finally begins to laugh again, prevents Batman from doing so.  The present day Riddler shows up next in 'Deathstroke #25' as a member of The Society who have placed Deathstroke on trial for appearing to have reformed. Riddler, using Hector Hammond's abilities, convinces the Society that Deathstroke is indeed evil by showcasing a simulation of Deathstroke killing them all right before Deathstroke himself is kidnapped.
Question: When was the relaunch?
Answer: in Batman #19.

Problem: Background: Namdev, also transliterated as Namdeo and Namadeva, (traditionally, c. 1270 - c. 1350) was a poet-saint from Maharashtra, India who is significant to the Varkari sect of Hinduism. He is also venerated in Sikhism, as well as Hindu warrior-ascetic traditions such as the Dadupanthis and the Niranjani Sampraday that emerged in north India during the Islamic rule. The details of Namdev's life are unclear. He is the subject of many miracle-filled hagiographies composed centuries after he died.
Context: The literary works of Namdev were influenced by Vaishnava philosophy and a belief in Vithoba. Along with the Jnanesvari, a sacred work of Jnanesvar, and of Bhakti movement teacher-writers such as Tukaram, the writings of Namdev form the basis of the beliefs held by the Varkari sect of Hinduism. He was thus among those responsible for disseminating the monotheistic Varkari faith that had emerged first in Karnataka in the mid-to-late 12th century and then spread to Pandharpur in Maharashtra.  Namdev and Jnanesvar used the Marathi language to convey their beliefs rather than using the traditional Sanskrit language that was essentially a buttress for the pre-eminence of the Brahmin priests. Namdev's style was to compose simply worded praise for Vithoba and to use a melodic device called samkirtana, both of which were accessible to common people. Shima Iwao says that "He taught that all can be saved equally, without regard to caste, through devotion (bhakti) to Vithoba" and that he greatly influenced groups of people who were forbidden by the Brahmin elite from studying the Vedas, such as women and members of the Shudra and untouchable communities.  The earliest anthological record of Namdev's works occurs in the Guru Granth Sahib, the Sikh scriptures compiled in 1604, although Novetzke notes that while the manuscript records of Namdev mostly date from the 17th and 18th centuries, there exists a manuscript from 1581 that presents a rarely recounted variant version of Namdev's Tirthavli, a Marathi-language autobiographical piece. It is evident that the Guru Granth record is an accurate rendition of what Namdev wrote: the oral tradition probably accounts significantly for the changes and additions that appear to have been made by that time. The numerous subsequently produced manuscripts also show variant texts and additions that are attributed to him. Of around 2500 abhangs that were credited to him and written in the Marathi language, perhaps only 600 - 700 are authentic. The surviving manuscripts are geographically dispersed and of uncertain provenance.
