Correctores Romani a congregation of cardinals and Roman theologians of thirty-five members, appointed by pope Pius V to revise the decretum Gratiani (see Corpus juris Canonici). Among the five cardinals who belonged to the college was Hugo Boncompagnus (subsequently pope Gregory XIII). The work was completed during the pontificate of Gregory XIII, who ordered the compilers to index all that had been collected, with regard to the decretum, by the congregation and by others, to invite all Catholic academies to cooperate in the work of revision, and to have all the former editions of the decretum compared. Gregory sanctioned the work July 1, 1580. — Wetzer u. Welte, Kirchen-Lex. 2:894.
