Simple and Parade armor of Philip IV when he was about 9. Part of a matching 6 suit set commissioned by Philip II for his 3 sons when they were 9, 7, and 5 respectively: Prince Philip, the future Philip IV; Ferdinand, the future Cardinal-Infante; and Don Carlos. circa 1614 [2240×1920]

Two sets of three suits of armor were made with identical decoration but differentiated to fit the measurements of each brother. In this way, the three children could be armed identically according to the two designed variants. In the first, simpler version, the decoration was limited to engraved and gilded perimeter bands, which ran along the edges of all the pieces, leaving the field plain. The second decorative variant, characterized by the fact that the field of the pieces is occupied by a dense network of lozenges housing trophies, except on the breastplate, where, following a rhomboidal distribution, they contain the double-headed eagle, a castle, a lion, and the Pillars of Hercules, all under the imperial crown. The ruff, meanwhile, displays the collar of the Golden Fleece.
