This study uses letters, tax records and other sources to study the maintenance of Lutheran clergy in Prussia between 1540 and 1570, concentrating on the example of the material life of the Ragnit pastor Martynas Mažvydas, namely his clothes, landholding, his parish and personal property, the sources of his income, his expenditure, his economic life, and his close and more distant personal connections. The example of this father of Lithuanian-language literature reveals the domestic aspect of the everyday life of Prussian Lutheran clergy.
