This Latin text was written by Swedenborg in 1761. It was first printed 12 years after Swedenborg's death, in 1784. An 1860 printing was edited by Tafel, probably by the Swedenborg Society in London (swedenborg.org.uk). We're not sure of the provenance of this text, and are researching it further. We received most of this text from the NewSearch project of the Academy of the New Church (brynathyn.edu), and the front matter courtesy of the Heavenly Doctrines Publishing Foundation (heavenlydoctrinepublishing.org).
