The Sun is nowadays observed using di?erent techniques that provide
an almost instantaneous 3-D map of its structure. Of particular
interest is the
studyofthevariabilityinthesolaroutputproducedbythedissipationofm-
netic energy on di?erent spatial and temporal scales - the
so-called magnetic activity. The 11-year cycle is the main feature
describing this phenomenon. Apart from its intrinsic scienti?c
interest, this topic is worth studying because of the interaction
of such processes with the terrestrial environment. A ?eet of space
and ground-based observatories are currently monitoring the
behaviour of our star on a daily basis. However, solar activity
varies not only on this decadal time-scale, as has been attested
mainly through two methods: (a) records of the number of sunspots
observed on the solar surface from 1610, and (b) the records of 14
10 cosmogenic isotopes, such as Cand Be, measured in tree-rings and
i- cores, respectively. The study of the long-term behaviour of
solar activity may be comp- mented by the study of historical
accounts describing phenomena directly or indirectly related to
solar activity. Numerous scienti?c and non-scienti?c d- uments have
reported these events and we can make use of them as a proxy of
solar activity in past times.
