Portret van de Friese arts Adolph Occo 1690

Dominicus Custos’ *Portret van de Friese arts Adolph Occo* (1690) is an engraving depicting a bust portrait of the titular Frisian doctor, surrounded by an oval frame. The inscription in the frame identifies Occo as a physician and details the year of his death (1590). The engraving, now at the Rijksmuseum, highlights the detail in Custos’ work through the depiction of Occo’s attire, from his fur-trimmed collar to the fine lines on his face. Custos’ portrait style was popular in the Netherlands, particularly in the engravings that he produced, making this piece a notable example of the artist’s work.
