Analyse grafic'orthodoxa, e demonstrativa, de que sem escrupulo do meno erro theologico, a escultura, e pintura podem, ao representar o sagrado mysterio da encarnacʹao, figurar varios anjos ...
A 1805 Portuguese treatise printed in Lisbon by the Impressao Regia, written by sculptor Joaquim Machado de Castro with Jose Lucio da Costa, arguing how sculpture and painting may depict angels around the Incarnation for church and scholarly readers. The pictures are plain engraved plates: one shows a heraldic ex libris with a compass-rose medallion and ribbon banner, the other a crowned Virgin on a pedestal flanked by two winged angels on clouds, drawn with fine hatching and a scale bar, useful for classical, devotional ornament.
