The word was first mentioned in 1651 & described as an #illness in 1688.
In 1710, it was claimed that music of Swiss #Alpine herdsmen & the Guggisberglied (a #folk song), led Swiss soldiers to desert. The singing of the same resulted (allegedly) in capital #punishment.
One doctor thought that the low air pressure made the Swiss sick with longing & would lead, if not returned home, to their eventual #death.
