[2][3] Peeters specialized in still-life paintings with food and was prominent among the artists who shaped the traditions of the Netherlandish ontbijtjes, "breakfast pieces," scenes of food and simple vessels, and banketjes, "banquet pieces" with expensive cups and vessels in precious metals.
[10] Some have suggested that in light of there not being any evident work by Peeters after 1621, she ceased painting after getting married, as for example Judith Leyster effectively did.
Because of the number of apparent copies of her work by various hands, some speculate that she may have headed a small school of artists.
[6] Peeters' first-known painting, signed and dated 1607, reflects the technical and compositional skill of a trained artist.
In addition, another seventy-six works are speculated to be in her oeuvre, although documentation is lacking to assign them affirmatively to Peeters.
[6] Several of her paintings, including two illustrated here, carry the signature represented as an engraved inscription on the side of the handle of the same decorated knife.
[5] She painted a set of four larger than usual (all 50‒51 × 71‒73 cm) still lifes, three dated 1611, that were in the Spanish royal collection by the following century (now in the Prado).
The Prado group were split between Spanish palaces in the 18th century, with the earliest inventory record for any being in 1734, when one was rescued in the fire that destroyed the Royal Alcazar of Madrid.
[6] In her works before 1620, Peeters was especially fascinated by the fall of light on metal objects – coins, goblets, pewter dishes, etc.
