Konstantinos, chartoularios and prokourator, 7th century. Seal (Lead, 22 mm, 11.36 g, 12 h). +KⲰN/CTANTI/N૪ XAPT/૪ΛAPI૪ in four lines. Rev. +KAI / ΠPOKOV/PATOP/OC in four lines. Unpublished in the standard references. Extremely fine.
The office of a prokourator, which is evidently a Greek transliteration of the Latin procurator, is extremely rare on Byzantine seals.
