1. A set of documents containing all the laws of a country or society.
2. A comprehensive treatise on a subject.

Pandects are compilations of Roman law consisting of selected passages from the writings of the most authoritative of the older jurists, methodically arranged, prepared by Tribonian with the assistance of sixteen associates, under a commission from the emporor Justinian.

This work comprises fifty books, and is one of the four great works composing the Corpus Juris Civilis. It was first published in A.D. 533, when Justinian gave it the force of law.
