Remarkably, Blytt, like Croll before him, used very long-period cycles in eccentricity to establish and validate his tuning.

This knowledge was maintained in relation to the calculation of Easter by monasteries when the Romans left, but developed little until Islamic astronomy came to Britain in the medieval period, and brought with it the classical texts.

The first half of the 20th century can best be regarded as an intermediate phase, despite the significant progress made in both theoretical aspects and tuning.

Astronomy – observation and theory – has been practiced in Britain* since prehistoric times.

Today astronomical tuning is widely accepted as numerical dating method after having revolutionised the age calibration of the geological archive and time scale over the last decades.

However, its origin is not well known and tracing its roots is important especially from a science historic perspective.

Newton and Flamsteed clashed over the running of the Royal Observatory.

Flamsteed wanted the observations to be the best possible, sought grants to make the best equipment and took time to develop the observing techniques.

The publication of these ideas compelled Charles Lyell to revise his Principles of Geology and add Croll's theory, thus providing an alternative to his own geographical cause of the ice ages.
