The Romans also demonstrated in their calendar, the implicit faith they placed in this distinction of days.  The fortunate days were marked in white, and the unfortunate in black; of these were the days immediately after the Calendae, the Nones, and the Ides; the reason was this:  in the 363rd year from the building of Rome, the military tribunes, perceiving the republic unsuccessful in war, directed that its cause should be inquired into.  The senate having applied to L. Aquinius, he answered, “That when the Romans had fought against the Gauls, near the river Allia, and had experienced so dreadful a defeat, sacrifices had been offered to the gods the day after the ides of July, and that the Fabii having fought on the same day at Cremera, were all destroyed.”  On receiving this answer, the senate, by the advice of the pontiffs, ordered, that for the future no military enterprise should be formed on the days of the calends, the nones, or the ides.  Vitellius having taken possession of the sovereign authority on the 15th of August, and on the same day promulgated some new laws, they were ill received by the people, because on that day had happened the disastrous battles of the Allia and Cremera.  There were other days esteemed unhappy by the Romans, such as the day of sacrifices to the dead; of the Lemuria; and of the Saturnalia, the 4th before the nones of October; the 6th of the ides of November; the nones of July, called Caprotinae; the 4th before the nones of August, on account of the defeat at Cannae; and the ides of March, esteemed unlucky by the creatures of Caesar.

In addition to these, were days which every individual considered fortunate or unfortunate for himself.  Augustus never undertook any thing of importance on the day of the nones.  Many historical observations have contributed to favour these superstitious notions.  Josephus remarks, that the temple of Solomon was burnt by the Babylonians on the 8th of September, and was a second time destroyed on the same day by Titus.  Emilius Protus also observes, that Timoleon, the Corinthian, gained most of his victories on the anniversary of his birth.  To these facts, drawn from ancient history, many from more modern times may be added.  It is said, that most of the successes of Charles V. occurred on the festival of St. Matthew.  Henry III. was elected king of Poland, and became king of France on Whitsunday, which was also his birthday.  Pope Sextus V. preferred Wednesday to every other in the week, because it was the day of his birth, of his promotion to the cardinalate, of his election to the papal throne, and of his coronation.  Louis XIII. asserted, that Friday was always a favourable day to him.  Henry VII., of England, was partial to Saturday, on which most of the happy events of his life had taken place.  Oliver Cromwell always considered the 3rd of September, 1650, when he defeated the Scotch at Dunbar; on that day, in the following year, he gained the battle of Worcester, but on the
