Yñigo Ortiz de Retez
Spanish explorer

Yñigo, Íñigo, or Iñigo Ortiz de Retes (fl. 1545) was a 16th-century Spanish maritime explorer of Basque origin, who navigated the northern coastline of the Pacific–Melanesian island of New Guinea and is credited with bestowing its current name (Latin: Nova Guinea; Spanish: Nueva Guinea).
Life
Early life
Yñigo Ortiz de Retes was born in Retes de Llanteno (Alava, Spain) in a non-titled nobility family (hidalgos) in the first decade of the 16th century. The first accounts we have of him are as part of Alvarado's expedition of 1538 to take the governorship of Guatemala and Honduras. He participated in the expedition to relieve the siege of Nochistlán in 1541 during the Mixtón war, led by Alvarado.
Villalobos Expedition
In 1542, he was appointed to the expedition of López de Villalobos to the Islas de Poniente (Philippines). Upon his arrival in Mindanao in February 1543, Ortiz de Retes was promoted to Maestre de Campo.
After the unsuccessful attempt of Bernardo de la Torre in 1543 to return to Mexico along a northern route, López de Villalobos commissioned Ortiz de Retes for the same mission but going south. On 16 May 1545, Ortiz de Retes, in command of the San Juan de Letrán, left port in Tidore, an island which was Spain's stronghold in the Maluku Islands and going by way of the Talaud Islands and the Schoutens, reached the northern coast of New Guinea, which was coasted till the end of August when, having got to the 5° S. latitude, contrary winds and currents forced a return to Tidore where he arrived on 5 October 1545. Many islands were encountered and first charted, along the northern coast of New Guinea, and in the Padaidos, Le Maires, Ninigos, Kaniets and Hermits, to some of which Spanish names were given.

Why this record matters
The phrase “spanish explorer” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 14, 2026. The linked authority identifier is Q291893. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1545, 1538, 1541 and 1542.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
