Ion Creangă

Context: At around the same time, Creanga also began attending Junimea, an upper class literary club presided upon by Maiorescu, whose cultural and political prestige was increasing. This event, literary historian Z. Ornea argued, followed a time of indecision: as a former Factionalist, Creanga was a natural adversary of the mainstream Junimist "cosmopolitan orientation", represented by both Maiorescu and Negruzzi, but was still fundamentally committed to Maiorescu's agenda in the field of education. Literary historians Carmen-Maria Mecu and Nicolae Mecu also argue that, after attending Junimea, the author was able to assimilate some of its innovative teachings into his own style of pedagogy, and thus helped diffuse its message outside the purely academic environment.  The exact date of his reception is a mystery. According to Maiorescu's own recollections, written some decades after the event, Creanga was in attendance at a Junimea meeting of 1871, during which Gheorghe Costaforu proposed to transform the club into a political party. The information was considered dubious by Z. Ornea, who argued that the episode may have been entirely invented by the Junimist leader, and noted that it contradicted both Negruzzi's accounts and minutes kept by A. D. Xenopol. According to Ornea's assessment, with the exception of literary critic Vladimir Streinu, all of Creanga's biographers have come to dismiss Maiorescu's statement. Several sources mention that the future writer was introduced to the society by Eminescu, who was an active member around 1875. This and other details lead Ornea to conclude that membership was granted to Creanga only after the summer break of 1875.  Gradually or instantly, Creanga made a positive impression by confirming with the Junimist ideal of authenticity. He also became treasured for his talkative and jocular nature, self-effacing references to himself as a "peasant", and eventually his debut works, which became subjects of his own public readings. His storytelling soon earned him dedicated spectators, who deemed Creanga's fictional universe a "sack of wonders" at a time when the author himself had started casually using the pseudonym Ioan Vantura-Tara ("Ioan Gadabout"). Although still in his forties, the newcomer was also becoming colloquially known to his colleagues as Mos Creanga ("Old Man Creanga" or "Father Creanga"), which was a sign of respect and sympathy. Among Ion Creanga's most dedicated promoters were Eminescu, his former political rival Iacob Negruzzi, Alexandru Lambrior and Vasile Pogor, as well as the so-called caracuda (roughly, "small game") section, which comprised Junimists who rarely took the floor during public debates, and who were avid listeners of his literary productions (it was to this latter gathering that Creanga later dedicated his erotic texts). In parallel to his diversified literary contribution, the former priest himself became a noted voice in Junimist politics, and, like his new friend Eminescu, voiced support for the group's nationalist faction, in disagreement with the more cosmopolitan and aristocratic segment led by Maiorescu and Petre P. Carp. By that the late 1870s, he was secretly redirecting political support from the former Factionalists to his new colleagues, as confirmed by an encrypted letter he addressed to Negruzzi in March 1877.
