He also reached great personal fame as a portraitist, being this field, the one that provided him with greater personal success, since still life was considered a lesser genre. He executed a portrait of Philip IV and worked during the 1620s in a series of portraits of the principal intellectuals and writers of his time, including: Lope de Vega, Francisco de Quevedo, Luis de Góngora, Jose de Valdivieso, Juan Pérez de Montalbán, Juan Ruiz de Alarcón and Francisco de Rioja. On van der Hamen's death, twenty of these portraits were inventoried as a single item among his belongings. The portrait of his older brother, Lorenzo van der Hamen, probably belonged to this series. The series itself was a focal point for philosophic speculation on the art of portraiture by some of the most distinguished minds of the time, who frequently praised Juan van der Hamen in verse and prose.
