A historical and scientific controversy has become a unique opportunity to discover the latest findings about this mysterious cloth preserved in the cathedral of Coria. This is explored through scientific examinations and studies, such as those carried out between 2006 and 2007 by members of the STURP team (“Shroud of Turin Research Project”) of NASA, led by Professor John Jackson. He maintains that the Holy Tablecloth of Coria and the Shroud of Turin were both present on the table of the Last Supper, a relic that commemorates the liturgy of the miraculous night of Holy Thursday, the sacramental origin of the Eucharist.
These studies were expanded by the director of the Turin Shroud Center of Colorado, supporting the argument—on documentary, cultural, and scientific grounds—that both cloths were used together: one placed underneath, the Holy Tablecloth of Coria, holding the tableware and food; and the other above, the Shroud of Turin, covering them as a symbol of purity in Jewish tradition, deeply linked to the laws of Kashrut, which seek both spiritual and physical purity. This is further supported by the similarities between the two textiles: both made of linen, with Z-twist weaving, comparable dimensions, and great antiquity
