Ducat - Anthony Fluvian St. John type

Anthony Fluvian served as Grand Master of the Hospitallers from 1421 to 1437, operating out of Rhodes at a moment when the Order's financial architecture depended heavily on Venice. The ducat struck under his tenure was directly modeled on the Venetian gold ducat — not merely in weight and fineness, but as a deliberate instrument of commercial credibility in Levantine trade networks where Venetian gold was the benchmark currency. Rhodes sat at the intersection of Christian and Ottoman merchant traffic, and an unrecognized coin was a useless coin.

Fluvian's tenure also saw the failed Ottoman siege of 1444 — or rather, he died before it, leaving his successor to face it.
