Along with other exiled Flemings, he made a career in Tudor London, painting allegorical images as well as portraits of the gentry and nobility.
[5] The original – signed with the "HE" monogram Eworth consistently used[6] — was donated to the Courtauld Institute of Art by Lord Lee of Farnham in 1932.
[10] However, after Mary I's death and the change of the political and religious atmosphere with the accession of Elizabeth I, Eworth in 1560 painted the Protestant Martyr Anne Askew, burned at the stake on charges of heresy.
[12] The allegorical painting Elizabeth I and the Three Goddesses (1569), with its slightly different "HE" monogram, has been variously attributed by Sir Roy Strong as cautiously to "The Monogrammist HE" in 1969[11] and more confidently to Joris Hoefnagel in 1987;[13] it is now accepted as the work of Eworth.
[15] Like many other artists of the Tudor court, Eworth was also engaged in decorative work; he was involved in the set design for a masque given by Elizabeth I in honor of the French Ambassador in 1572.
