Grandsire

[4] The plain course of Grandsire Doubles is shown, but it extends only to 30 different rows or changes.

[6] Grandsire is usually an odd-bell method and the following suffixes are used to describe it when the changes are rung on different numbers of bells.

The method was devised around 1650, probably by Robert Roan who became master of the College Youths change ringing society in 1652.

[7] Details of the method on five bells appeared in print in 1668 in Tintinnalogia, the first book to be published on change ringing.

William Henry Thompson, a mathematician, proved in a paper published in 1880 that it was impossible to achieve the 5040 changes using the normal bobs only, without the use of singles or some other type of call.

[8] Peal length round blocks of caters and cinques were more easily achieved.

According to the best available knowledge in 2017, 6,929 peals of Grandsire Caters (on 10 bells) were rung in the 300 years after 11 January 1711.

Grandsire Caters was the leading 10-bell method in each decade from 1711 to 1890, but Stedman Caters has proved more popular recently and on 9 July 2010 its cumulative peal total from 1711 pulled ahead of the running Grandsire total.
