The two women allegedly told police that they daubed the works with oil and myrrh “because the Holy Scripture says it is miraculous,” the authorities said.
A guard at the National History Museum in the Old Parliament building recognized the women following the release of photographs distributed by police to all museums and sites from the CCTV footage of their previous “oil attacks”.
Police were called and the two women were subsequently arrested while touching one of the exhibits and holding a bottle of oil, which they were intending to use.
They will appear before prosecutors on Monday.
In July, two middle-aged women left oil marks on dozens of items at the Byzantine and Christian Museum, which is home to the country’s most extensive collection of religious relics.
