Why Gerbert of Aurillac added to the letter to brother Adam the clime table where the longest day of the year reaches 18 hours?
Original language description
This paper tries to solve the question why did Gerbert of Aurillac in his brief letter to brother Adam (written in 989) elaborate a table for climate (horologium) where the longest day of the year reaches 18 hours. The standard summaries of climates, available during Gerbert?s time, didnot mention such climate. Gerbert added this table to his letter because the table of clime with 18 hours solstitial day (similarly like the second added table for the climate of Hellespont) is an exemplary guideline according to which Adam can make his own horologies. Gerbert used this extraordinaryclimate as a suitable explanatory example due to its mathematical simplicity appropriate demonstrating the astronomical theory of yearly Sun movement.
