Issued in 1972 to mark the 500th death anniversary of Cardinal Bessarion, this beautifully engraved three-stamp set honors the Greek scholar, humanist, and Church leader who played a key role in bridging Eastern and Western Christianity. The L.40 green stamp depicts a Renaissance scene symbolizing scholarship and ecclesiastical dialogue. The L.90 red features a finely detailed portrait of Bessarion, while the L.130 black illustrates his heraldic coat of arms. Printed by I.P.S. Roma in classic Vatican engraving style, this set is prized for its sharp linework and historical depth. A strong addition for Vatican, Renaissance, and Church history thematic collections.
