A hand-written note has been found buried inside the bum of an ancient Jesus Christ's statue, a development which has sparked wonderment.

Restorers of an 18th century statue of Jesus Christ in Spain have found a hand-written note hidden up his bum.

The message written carefully in calligraphy message dating back to 1777, had been put stuffed up the Messiah’s backside by a priest preserving it like a time capsule.

It contains key information about the period and details on popular pastimes, the economic situation, political and religious matters, famous people, and other topics.

The document is signed by Joaquin Minguez, priest of the cathedral of Burgo de Osma at the time, and was recently unearthed by workers of the restoration company Da Vinci Restauro.

Today, the wooden statue is kept at the church of Santa Agueda in the village of Sotillo de la Ribera in the northern Spanish province of Burgos.

The document, carefully-handwritten on both sides of two pages, was found when restorers removed a piece of fabric used to cover Christ’s behind which exposed a small gap

Local historian Efren Arroyo was overwhelmed by the discovery: "It is amazing, because it really is unique to find hidden handwritten documents inside such statues."

As well as naming the statue’s sculptor and including data on local information ranging from agricultural matters to community affairs, the document highlighted common diseases, popular children’s games and even the names of popular bullfighters of the time.

According to experts, all these references indicate Joaquin Minguez’s intention to make one of the earliest time capsules ever left behind for future generations to discover.
