At about the same time super-sized bombards were phased out in Western Europe, the technology was transmitted to the Ottoman army by one Orban, a Hungarian gunfounder, on the occasion of the Siege of Constantinople in 1453. The extant Dardanelles Gun, cast by the Ottoman gunfounder Ali several years later, is assumed to have followed closely the outline of Orban's guns. A similar super-sized bombard was employed by the Ottoman navy aboard a carrack of possibly Venetian design at the Battle of Zonchio in 1499.
