Another result of the surplus of (sometimes disillusioned) clerical students was the appearance of the Latin writings of the Goliards and wandering clerics (clerici vagantes). There began to appear more cynical and heretical parodies of the Mass, also written in ecclesiastical Latin, known as "drinkers' masses" and "gamblers' Masses," which lamented the situation of drunk, gambling monks, and instead of calling to "Deus" (God), called to "Bacchus" (the God of Wine) and "Decius" (the god of dice, which were used in gambling). Some of the earliest of these Latin parody works are found in the medieval Latin collection of poetry, "Carmina Burana", written around 1230. At the time these wandering clerics were spreading their Latin writings and parodies of the Mass, the Cathars, who also spread their teachings through wandering clerics, were also active. Due to the proximity in time and location of the Goliards, the Cathars, and the witches, all of whom were seen as threatening the authority of the Roman Catholic Church and the Papal Authority in Rome, some historians have postulated that these wandering clerics may have at times offered their services for performing heretical, or "black" Masses on various occasions.
