The programme took 10 years to develop: it automatically counts the threads of a canvas, which makes it possible to refine attribution and dating. With its help, a painting attributed to Francisco Rizi in a 2023 exhibition has been reattributed to Francisco Herrera the Younger.

The programme can be used on the [museum's website](https://www.museodelprado.es/recurso/aracne-estudiando-los-lienzos-de-los-cuadros/b44d6af3-3f35-51b7-2d10-aff52ec27915?ref=theparnassian.com)
