Hyeronimus Custodis was a portrait painter active during the Elizabethan era of English history, known primarily for his work as part of the circle of artists sometimes referred to as the 'English School'. His exact birth and death dates are not documented, but he is known to have been active as an artist from 1589 onwards. Custodis is one of the lesser-known painters of the period, overshadowed by contemporaries such as Nicholas Hilliard and Isaac Oliver who were renowned for their work in miniature painting.
Custodis was of Flemish descent, and his style suggests he was trained in the traditions of the Low Countries, which had a significant influence on English art during the 16th century. He was one of the artists employed by the Elizabethan court, and his clientele included several high-profile figures of the time. His work is characterized by a somewhat rigid and formal approach, with a focus on detailed costume and adornment, reflecting the fashion and status of his subjects.
Although Custodis's output was modest compared to that of his contemporaries, some of his works have been preserved and provide insight into the portraiture of the Elizabethan era. His portraits are important historical documents that contribute to our understanding of the period's aesthetics and the self-fashioning of the Elizabethan nobility. Unfortunately, due to the limited number of surviving works confidently attributed to him, much about his life and the full extent of his oeuvre remains unknown. His death date is also unrecorded, and he appears to have ceased activity around the end of the 16th century.
