Arduino Scola, an 80-year-old retired carpenter, died on Thursday morning, while his sister Silene, 84, died eight hours later, Il Gazzetino reported.
The siblings had lived next door to eachother in Santa Giustina in Colle.
Arduino, described as a "quiet man of good humour", was admitted to hospital eight days before for the treatment of hernia, while his sister, an unmarried embroiderer, died of pneumonia.
Both died at Camposampiero hospital. Silene passed away before knowing that her brother had died.
“On Thursday morning, at around 8am, my father died, and shortly after I went to see Aunt Silene in another ward", Sandra Scola, Arduino’s daughter, told the newspaper.
"My aunt opened her eyes...but was no longer present and did not hear of her brother’s death. Then she died in the afternoon.”
Silene, who lived with a sister, was described as someone of “of few words” but who was “very religious and active in the parish” and “well-liked” by all, the newspaper added.
