[1][2] According to Spanish art historian Juan Agustín Ceán Bermúdez (1749-1829), Amaya was a disciple of Vicente Carducho (1576/78–1638).
They lived "outside the Puerta del Campo"; that is, roughly in the area of the modern Plaza de Zorrilla [es] in Valladolid.
[1] Ceán Bermúdez said of Amaya, "tienen mejor gusto de color que correccion en el dibuxo" ("he had better taste in colour than in correctness of drawing").
[3] The one authority cited by Ceán Bermúdez was Antonio Ponz (1725–1792), who may only have known Amaya's altarpiece at Iglesia de San Martín, Segovia [es].
[4] So had the anonymous author who wrote for the National Museum of Sculpture, Valladolid in 2001, "Fue artista bien preparada para la composición, mostrando gran habilidad en la angrupación y relación de las figuras" ("He was a masterful artist in composition, showing great skill in the grouping and relationship of people").
