Spiš Castle
Martinuzzi moved to the court of Hedwig of Cieszyn in Szepes Castle (now Spiš Castle in Slovakia) around 1503. She was the widow of his father's patron, Count Stephen Zápolya. Initially, he served as a page, then he was made a guard of the palace. He decided to abandon his military career and entered the Pauline Order at the age of 24. He most probably settled in the Budaszentlőrinc Monastery where he learnt to read and write. He was sent to continue his studies in the Jasna Góra Monastery in Częstochowa. He was made the head of the monastery, according to unproved theories. After he returned to Hungary in 1527, he became the prior of the Sajólád Monastery, which had recently received grants from the Zápolyas.
