Grossetto - Jacob Gattilusio Y

Jacob II Gattilusio ruled Lesbos as a Genoese client lord during one of the more turbulent stretches of Aegean history — the decade immediately following Timur's crushing defeat of the Ottomans at Ankara in 1402 briefly reopened the question of who would dominate the eastern Mediterranean. The Gattilusio family, installed on Lesbos by a marriage alliance with the Byzantine imperial house in 1355, navigated this uncertainty by maintaining careful tributary relationships with whichever power was ascendant.

At 0.52g, this grossetto sits at the lighter end of the family's silver issues — Schlumberger's XVI, 13 classification places it within a group showing notable weight variation across surviving specimens.
