Caldonazzo was the son of Giacomo (or Jacobus) de Caldonazzo, Baron of Ivano, and Laura della Volpe de Vicenza. The Caldonazzo family were long-established as part of the nobility of the
South Tyrol. In 1468, following the death of Giacomo, his widow transferred the castle at Ivano to
Archduke Sigismund of Habsburg, ruler of the
Tyrol, in exchange for the payment of a pension. Sigismund's cousin,
Maximilian of Habsburg, son of the
Holy Roman Emperor, Frederick III, became ruler of Tyrol in 1490 and, in 1492, Antonio de Caldonazzo and his brother Hans renounced to him their remaining rights to the Barony of Ivano. Maximilian succeeded his father on the latter's death in 1493 and became
Holy Roman Emperor as Maximilian I. Caldonazzo appears to have become a
favourite of Maximilian, playing a prominent part amongst a group of courtiers and others closely associated with the Emperor’s enthusiasm for and participation in
jousting and
tournaments generally. He developed a key role in Maximilian’s court as a jousting competitor and, indeed, Maximilian seems to have particularly enjoyed jousting with him. There are surviving records of Maximilian and Caldonazzo jousting with each other in at least three tournaments: at
Linz in December 1489 and January 1490 and at
Innsbruck in March 1498. Caldonazzo’s jousting prowess was exhibited at the celebrated tournament held at the wedding of
Wolfgang von Polheim and Johanna van Borsselen in
Mechelen in 1494 where he was considered to have been the overall tournament champion. Caldonazzo received a number of favours and appointments from Maximilian. By 1490, he had been appointed as an Imperial Councillor and as
Truchsess (a type of
seneschal responsible for imperial dining). In 1498, he was given the office, jointly with his brother Hans, of
Pfleger (or administrator) of
Landeck. In 1501, Maximilian granted him the estate of , a village on the
Danube near
Vienna. Caldonazzo was married to Apollonia von Winden and died . The coats of arms of Caldonazzo and his wife, with their names, are inscribed in an arch over the western entrance of the to mark donations they had made. == Maximilian's
