Painting with gold
Artists' Techniques
Gold paint enriches many draperies, where it is shaded in pink with an organic colourant and sometimes in blue with indigo.
Gold highlighting in the 'camaïeu d'or' technique has been used for blue and pink drapery folds and for other details.

The rectangular panel in the upper border above the text block shows the Arma Christi, the Instruments of Christ’s Passion (pincers, hammer, cross with crown of thorns, nails, lanterns, scourges, dice, whips, column with ropes, ladder, and rooster). It was customary for children to make the sign of the cross and to say the words In nomine Patris, et Filii, et Spiritus Sancti, Amen (‘In the name of the Father, and Son, and Holy Spirit, Amen’) before reciting their ABCs. Here, the cross of the Arma Christi extends into the text block, just before the A of the alphabet, to prompt Claude to perform this devotion.
The large brush strokes in the azurite blue sky of the upper right scene hide a pentimento, invisible even in the near-infrared image because azurite still absorbs light at these wavelengths (800-1000 nm). Infrared reflectography, however, reveals the presence of small pointed arches, and the different shape of the clouds below God the Father’s feet (hotspot 3).
