"On the venerable day of the Sun let the magistrates and people residing in cities rest, and let all workshops be closed. In the country however persons engaged in agriculture may freely and lawfully continue their pursuits because it often happens that another day is not suitable for grain-sowing or vine planting; lest by neglecting the proper moment for such operations the bounty of heaven should be lost." *
* Given the 7th day of March, Crispus and Constantine being consuls each of them for the second time. Codex Justinianus, lib. 3, tit. 12, 3; translated by Philip Schaff, History of the Christian Church, Vol. 3 (1902), p. 380, note.
