Based on depictions of the five keystones on the gate of the Old Town Hall in Bratislava (Pressburg),[2] historian Antal Pór identified her as Elizabeth, the daughter of Gurke, a member of the noble Csák kindred.

[4] Despite Coloman's illegitimacy, Charles favoured him and arranged for his education to be overseen by Bishop Ivánka of Várad, allowing him the use of the title "prince" and the Hungarian royal seal of the House of Anjou.

[2] The long-time reigning bishop Nicholas Kőszegi, who had become embroiled in conflict with Charles I several times, died in the late spring-early summer of 1336.

The details of the alleged conspiracy, including its factuality, are unclear: historians have debated whether Coloman harboured ambitions against his half-brother the king, or was merely the victim of political persecution.

[1] This event provoked the reigning pope, Innocent VI, to launch an investigation of his case, entrusting Vásári and Arnošt of Pardubice, Archbishop of Prague.

A missive from Pope Urban V on 3 September 1364, requesting him to take part in brokering a peace between Ordulf, the archbishop of Salzburg, and Duke Louis VI of Bavaria, indicates that Coloman had subsequently been restored to the good graces of the papacy.

[2] Coloman vigorously defended his bishopric's interests; when the residents of Vica (today a borough of Beled) intended to erect a separate chapel, the bishop ruled in favor of his protege, the parish priest of Szentandrás.

[2] Sometime around 1343, there was also a conflict of jurisdiction between Coloman and the powerful lord Paul Nagymartoni, when the latter – bypassing the bishop – turned directly to Pope Clement VI to request the assignation of the bishopric tithe of Nagymarton (Mattersburg, Austria) to the local parish church he had just founded.

His first known seal (68x42 mm, 1345) depicts Mary, sitting in a tabernacle-like closed canopy, who holds a scepter in her right hand, with the child Jesus standing on her left knee.

Coloman's second seal (77x50 mm, 1355, 1356) depicts the Coronation of the Virgin: Mary is crowned by her son Jesus, who holds a book in his left hand.

The mass of their upper level is broken down by tracery windows, the lower ones are transformed into two completely pierced, columnar tabernacles, in which two kneeling angelic figures facing the scene take place.

It is plausible that Coloman's second seal represents a Southern German (Swabian) cultural impact, which affected Central European artistic representations.

Besides the cardinals and the archbishops of Esztergom, Coloman is the only known prelate in Medieval Hungary, who used a ring seal (70 mm) with a helmeted coat-of-arms the circumscription "+S-DOMINI COLOMA-------IENSIS".
