Resumo

Este estudo concentra-se na aplicação de uma abordagem multianalítica que combina técnicas de processamento de imagens, estudos de imagem e caracterização de materiais num Incunábulo francês do final do século XV e princípio do século XVI: o BPE, Inc. 438. O primeiro objetivo do estudo foi verificar o potencial dos métodos computacionais em imagens de NIC para recuperar reconstruções precisas de impressões de gravura por Germain Hardouyn. Para isso, como Trindade, f.8r; San Antonio Abad, f.61v. A metodologia aplicada permitiu a criação mais rápida de reconstruções digitais, enquanto a análise do material demonstrou o uso de azurite, malaquite, vermelhão, chumbo branco e ocre, e sua resposta NIR foi avaliada no contexto do processamento digital. O segundo objetivo era fazer uma comparação entre as iluminações escolhidas e as referências registradas das mesmas representações de dois incunábulos da Biblioteca Britânica, desenrolando um plano de alteração planejado seguido pelo iluminador insistindo em critérios visuais e teológicos.
