Legend has it that this relic arrived in Portugal in the possession of Princess Vataça Lascaris, and today is (and on exhibition at the Royal Treasury in the Basilica of Castro Verde).
Eudoxia, still a child, married in 1261 in Constantinople with Count Pedro of the House of Ventimiglia and Tende (a region that retains the Byzantine double-headed eagle as a symbol), traveling then to Liguria.
