on which the movable new year's day then happened to fall, and were
numbered from the year following the last of Cleopatra, as from the
first year of the reign of Augustus. But notwithstanding the many
advantages of the Julian year, which was used throughout Europe for
sixteen centuries, till its faultiness was pointed out by Pope Gregory
XIII., the Egyptian astronomers and mathematicians distrusted it from
