In 2013, Argentina's then-President Cristina Fernández de Kirchner sparked controversy for her decision to replace a monument of Christopher Columbus in Buenos Aires with one of nineteenth-century mestiza revolutionary Juana Azurduy. This article examines the history and iconography of these monuments, exploring the intersections between public space, art, politics and memory. It argues that these monuments — one representing Argentina's previously maligned Italian immigrant heritage, the other its forgotten indigenous culture — demonstrate how fundamental struggles over national identity have been embedded and contested in the capital's urban landscape, in ways that remain influential. It highlights Argentina's 1910 centennial and 2010 bicentennial as key to these efforts, and examines the power/politics of place in the central plaza where various actors have fought for public commemorative representation.

This study is a brief report of the only re-sailing of Columbus' 1492–1493 Voyage following the data in his log in a scientifically controlled research voyage by a professional and experienced global and ocean navigator. The study is follow-on to the article: “The Controversial Skill of Columbus as a Navigator: An Enduring Historical Enigma,” published in The Journal of Navigation (2009) Vol. 62, 417–4251.

This study of Columbus' navigation is unique because it was written by an historian who is also a trained and experienced professional global (and ocean) navigator, rather than an academic historian with only superficial knowledge of the science of navigation as practiced by Columbus and other early navigators. The study is also unique in that as an American historian author disagrees with his colleagues in the USA who present the “politically correct” view of Columbus as an unskilled entrepreneur who obtained his limited knowledge of navigation as a crew member or passenger on Portuguese voyages, rather than as one of the most skilled and experienced of the cadre of respected Genoese captains and navigators used by kings throughout Europe to perform their maritime enterprises.
