Colloquies (Latin title Colloquia familiaria) is one of the many works of the "Prince of Christian Humanists", Desiderius Erasmus. First published in 1518 as Latin dialogues for schoolboy exercises, the work expanded over the following decades with witty but more serious and controversial content. Among other things, the pages "...held up contemporary religious practices for examination in a more serious but still pervasively ironic tone". Colloquium in Latin means a conversation or discussion. Source: Wikipedia (en)
