'''Bastille''' is a sequence of [[mos scale]]s supported by [[1407edo]] and [[1789edo]]. It derives its name from the fact that the storming of Bastille happened on 14 July 1789, which in date format is written as 14/07/1789.

The defining characterstic of Bastille is that the generator is a "meantone" flat fifth of around 694.5 cents~~. Such a characteristic is quite remarkable for edos in the thousands to support~~.

The defining characterstic of Bastille is that the generator is a "meantone" flat fifth of around 694.5 cents.

The [[The Jacobins #Pure Bastille|1407eff & 1789 temperament]], named ''pure bastille'', tempers out the [[jacobin comma]], which brings two great French Revolution terms in one temperament. However, from a just intonation perspective, such temperament may be too complex, even for edos in the thousands. On the other hand, taking patent vals of 1407edo and 1789edo in the full 13-limit produces a temperament whose fifth is mapped to [[112/75]], a relatively simple interval on this scale. Comma basis for this version of bastille is {384912/384475, 41765625/41746432, 4501875/4499456, 540078539/540000000}.

The common thing between the two temperaments is that fifteen stacked generators lead to [[5/4]]. Given the precision, such a characteristic is quite remarkable for edos in the thousands to support.
