Plentiful donor inscriptions show that most new church building programmes; mosaics, roofs, furnishings, were financed by private donations. The costs of maintenance and lighting, however, fell on the general fund. This also applied to the churches, known as tituli, served directly by the bishop's clergy, generally also including any surviving house churches from the period before the Peace of the Church and the rural baptistery churches; but not to the chapels, called parochiae, established by rural landowners for the convenience of their tenants.
