Aurelijus Rūtenis Antanas Mockus Šivickas (Spanish pronunciation: [anˈtanas ˈmokus]; born 25 March 1952) is a Colombian mathematician, philosopher, and politician.

These tended to involve grand gestures, including local artists or personal appearances by the mayor himself—taking a shower in a commercial about conserving water, or walking the streets dressed in spandex and a cape as Supercitizen.

Mockus resigned from the Green Party in June 2011 because he opposed its Bogotá mayoral candidate being supported by former right-wing President Álvaro Uribe.

Famous initiatives included hiring 420 mimes to make fun of traffic violators, because he believed Colombians were more afraid of being ridiculed than fined.

When Mockus ran again for the 2001 mayorship, he held a ceremony in a public fountain "to ask forgiveness for leaving the mayor's office in an unsuccessful bid for the presidency."

In November, Mockus made a special trip to the University of Virginia to speak about the use of positive social mechanisms in relation to his tenure as the mayor of Bogotá.

He is the president of Corpovisionarios,[citation needed] an organization that consults to cities about addressing their problems through the same policy methodology that was so successful during his terms as Mayor of Bogotá.

Mockus, Peñalosa and Garzón embarked on an innovative campaign, in which they acknowledged and honored each other's qualifications and preparedness for the job, and telling people to choose whomever they liked best.

Through a popular consultation carried on 14 March 2010, which he won by a large margin, Mockus became the Colombian Green Party presidential candidate.

On 4 April 2010, Antanas Mockus chose Medellín's former mayor Sergio Fajardo as his running mate, unifying two groups at the center of the political spectrum.
