- The Nobleman with His Hand on His Chest (1580): One of El Greco’s most iconic portraits, this painting conveys dignity, mystery, and psychological depth. The identity of the sitter remains uncertain, adding to its intrigue.
- The Holy Trinity (1577–1579): A masterpiece of religious emotion, this altarpiece combines Italian Mannerist influence with the expressive spirituality that defines El Greco’s mature style.
- The Adoration of the Shepherds (1612–1614): This late work, possibly intended for the artist’s own tomb, is a swirling, ecstatic depiction of divine light and earthly reverence.
- Saint Andrew and Saint Francis (1595–1598): A powerful juxtaposition of two saints, demonstrating El Greco’s skill in conveying spiritual intensity and inner character.
