October, 1582, so that the fourth day of the month was followed immediately by the fifteenth.

The Nineteen Years' Course of the Golden Number. This course or cycle was invented by an Athenian astronomer about 433 B.C. It was not exact, but was hailed with delight by the Greeks, who adorned their temples with the key number, done in gold figures; hence the name. The cycle of course is the revolution of nineteen years, from 1 to 19. When this revolution or course of years is run there is a new beginning in marking, No. 1, e.g., in the year 1577 the nineteenth number, the golden number, was 1; the following year it was 2, and so on until in 1597 the golden number again is 2. A table given in the Breviary shows how the golden number may be found and a short rule for the finding of it in any year is given. To the number of the year (e.g., 1833) add 1; then divide the sum thus resulting by 19 and the remainder is the golden number; if there be no remainder the golden number is 19.
