Sacred Heart of Jesus (Sagrado Corazón de Jesús) by Francisco Eduardo Tresguerras (1759–1833), Mexican Neoclassical architect, painter, sculptor, and engraver, is an oil-on-canvas devotional work housed in the Museo de Arte de Querétaro (MAQRO). The composition centers Christ half-length within a painted trompe-l'œil oval frame, dressed in a pale blue robe, his gaze directed outward toward the viewer. Both his hands gesture toward his radiant, flaming heart at chest level, crowned with thorns and topped by a small cross, the whole encircled in golden light against his robe. A halo of fine rays surrounds his head, while above, a dove ; representing the Holy Spirit ; descends amid dense grey clouds, a beam of light connecting it directly to Christ's heart. In the upper corners, a chalice and host appear at left and an illuminated cross at right, framing the scene symbolically.
Below the oval frame, Tresguerras arranges a still-life of the Arma Christi, the instruments of the Passion: a reed staff, rope, dice, pincers, and other implements scattered across a stone ledge. A painted scroll at the bottom bears a Latin inscription — Nunquid est cor tuum rectum, sicut Cor meum cum corde tuo? — cited as IV Reg. 10:15, a Vulgate reference to the Second Book of Kings, where Jehu asks Jehonadab "Is your heart right, as my heart is with your heart?" repurposed here as Christ's direct address to the viewer.
Tresguerras combines traditional Catholic iconography with a relatively direct and organized composition. The oval framing isolates the sacred figure from the surrounding space, creating an intimate devotional image intended to encourage prayer and contemplation. The subject reflects the importance of Sacred Heart devotion in New Spain, where religious imagery played a significant role in communicating Catholic theology. Artists used recognizable symbols to reinforce the legitimacy and historical foundations of the devotion, which faced theological challenges during the eighteenth century.
