The Wellcome Trust currently has an exhibition until 26th February 2012 of Mexican miracle paintings.
These paintings, called ex-votos or retablos are dedicated to saints as a way of showing gratitude for being saved from illness, accidents and other disasters.
The little guide provided by the gallery describes the retablos as 'humble expressions of thanks for reprieve from the trials of life, they bear witness to a deep-seated faith and a common humanity.'
The trust has 100 of them on display and I found the collection very moving.
