To the astronomer the Moon has indeed been a friend of old standing;

The reasons, originally, have been utilitarian rather than scientific; as the apparent motion of the Moon was so intimately connected with the calendar and time keeping for agricultural and cultic purposes. Until the advent of modern astronomy in relatively recent times, the ob
