Cinnabaric

The cinnabaric rock in this mine was mostly composed of upper lias jaspers (phthanites), siliceous rock par excellence.

Under the intensely white mural of the church, crowned by a cinnabaric cornice, and enlivened by the color-spot of the medallion, are congregated figures of darkly painted monks from whom are reflected the cinnabaric and the bright-green colors of the angelic figures.
