William (Goulēelmos), patrikios, circa 1050-1100. Seal (Lead, 31 mm, 16.88 g, 12 h). MHP - ΘV Nimbate Mother of God 'Episkepsis', raising both hands in prayer, medallion of Christ in front. Rev. +KЄ R,Θ, / TⲰ CⲰ Δ૪ / [Γ]OVΛHЄΛ/MO ΠATPI/KIⲰ in five lines, decorations flanking the last line. Apparently unpublished save for its previous auction appearance, but cf. Cheynet, Istanbul 2.238 (for a seal of William as patrikios and strategos). A historically interesting seal of a westerner serving the Byzantine empire. Somewhat rough, otherwise, extremely fine.
