O-mata-ah-luta (Red Plume)

O-mata-ah-luta, or Red Plume, was a Lakota leader whose portrait Shindler painted in 1887 as part of the ongoing Smithsonian documentation project. The name Red Plume likely refers to a war honor or personal medicine object of significance to the individual. The systematic nature of the Smithsonian portrait project means that Shindler often painted multiple sitters in the same session, producing a set of related works that read as a collective portrait of Lakota political leadership during one of the most critical periods of their history.

Consistent with his other Smithsonian commissions, Shindler places Red Plume in near-frontal pose against a neutral background, with careful rendering of the face and detailed attention to regalia. The technique is competent academic portrait painting serving a documentary function rather than pursuing stylistic distinction.
