[2] Literary historian László Mezey argued Lawrence studied at Laon, France during his youth, identifying him with that "Laurentius Pannonus", who enrolled in the university in 1100.

[1] 17th-century Jesuit scholar Sándor Szörényi claimed Lawrence served as Bishop of Eger from 1104 to 1105 prior to his election as metropolitan of Esztergom, but there is no contemporary record of that.

Nevertheless, numerous authors, including Márton Szentiványi, György Pray and Miklós Schmitth accepted the data in the upcoming decades.

[4] Under his tenure, he was a strong confidant of Coloman and advocated his foreign policy in the assistance of Pope Paschal II in the long struggle with the Holy Roman Emperors over investiture.

The contemporaneous Cosmas of Prague referred to Lawrence as a living person at the beginning of the Stephen's reign, when the young king provocated a war against Vladislaus I of Bohemia, as the Czech chronicler narrated in his work Chronica Boemorum.

[9] According to Monika Jánosi, the first synod summoned by 1112 at the latest, just before the establishment of the Diocese at Nyitra (Nitra), when the numbers of Hungarian bishops raised to twelve.

[10] As Thoroczkay notes, the description of the Chronica Hungarorum (ten bishops) is exaggerated, which reflects the Archdiocese of Esztergom's aspirations to become the only Metropolitan province.

The First Synod of Esztergom was influenced by the resolutions of the Councils of Piacenza (1095) and Poitiers (1100),[12] while Lawrence and his prelates also utilized the texts of the Pseudo-Isidorian Decretals and the Collectio Dionysio-Hadriana.

Medievalists László Koszta and Gábor Thoroczkay identified the synod with that meeting in Esztergom, where Cuno excommunicated Henry V, Holy Roman Emperor for the brief imprisonment of Pope Paschal.

The first three points strengthened the royal power in order to support Coloman against his claimant brother Álmos, who took assistance from the Holy Roman Empire.

[17] This rivalry also appeared in the coeval Life of King Stephen of Hungary, compiled by Hartvik, Bishop of Győr (thus a subordinate to Lawrence), when it derived the title of the superior of Kalocsa from Esztergom, emphasizing its subsidiarity.
