A useful handbook of Swedenborg's theology is the Compendium of the Theological Writings of Emanuel Swedenborg by the Rev. Samuel Warren (London, 1885).
In this as in the previous studies a compendium is learned by heart, and explanations are given from commentaries and noted down by the students word for word.
He founds his argument mainly on passages in the Communia Naturalium, which indeed prove distinctly that it was sent to Clement, and cannot, therefore, form part of the Compendium, as Brewer seems to think.
The Speculum Majus, the great compendium of all the knowledge of the middle ages, as it left the pen of Vincent, seems to have consisted of three parts only, viz.
Ambrosius Macrobius Theodosius (c. 400) wrote a treatise on Cicero's Somnium Scipionis and seven books of miscellanies (Saturnalia); and Martianus Capella (c. 430), a native of Africa, published a compendium of the seven liberal arts, written in a mixture of prose and verse, with some literary pretensions.
