In the 18th century, judicial protocols evolved in accordance with precisely defined rules of criminal law and were
strongly influenced by the interrogators. A critical reading of the historical source discussed in this article, in which all
rules and elements of material and formal criminal law are taken into consideration, enables us to follow the life of Matevž
Kaučič. In his youth, Matevž played numerous roles: his family renounced him, he was a beggar and a herdsman, a cheerful
fellow and a drunkard, and occasionally a thief and idler, and a man who travelled great distances. Short descriptions of his
thefts reveal the numerous skills he used to survive and to circumvent the various formal and informal means (established
by patents and ordinances) of supervising individuals and the community in effect in his time.
