Didacus automaton (nonfiction)

Mechanical automaton of Didacus of Alcalá, commissioned by King Philip II of Spain

The Didacus automaton is a mechanical model of Didacus of Alcalá, commissioned by King Philip II of Spain.

King Philip commissioned Juanelo Turriano, mechanic to Emperor Charles V, to build the clockwork model of Didacus.

The model performs a number of set actions, including the beating of the breast which accompanies the Mea culpa prayer.

It is still in working order and can be seen in the Smithsonian Institution.

Historical theories for why the friar was built include that: Philip II wished to share the miracle of his son's recovery with his people; or the clockwork friar provided a portable model of "how to pray" which could be displayed around the kingdom.
