ca. 1555

[Possible/Probable] “Ordinance Requiring Jews to Wear A Badge” issued by Duke of Candia [Present-day Greece]
Commentary from other sources:
1) In Candia (Crete), then under Venetian rule, Jewish shops had to be distinguished by the badge. David d’Ascoli, who published in 1559 a Latin protest against the degrading regulation, was severely punished and his work was destroyed.
