De Constantia in publicis malis (On constancy in times of public evil) was a philosophical dialogue published by Justus Lipsius in two books in 1583. The book, modelled after the dialogues of Seneca, was pivotal in establishing an accommodation of Stoicism and Christianity which became known as Neostoicism. De Constantia went through over eighty editions between the sixteenth and eighteenth centuries. Source: Wikipedia (en)
