Blacksmith Johann Schmidberger works on a suit of armour for the Vatican's Swiss Guards at his workshop in Molln, Austria, March 29, 2017. Austrian blacksmiths who produce ceremonial suits of armour for the Vatican's Swiss Guards are close to the end of their current deal to do so, and say supplying the suits will not now be an issue for many years to come. One of the drawbacks of the Swiss Guards' medieval uniforms is that the craftsmanship needed to make them is disappearing. (Photo by Leonhard Foeger/Reuters)

The city of Meroë laid undiscovered for two millennia before British archaeologist John Garstang excavated it in the early 20th century. Garstang took the radical decision to document his discoveries with photography – and immortalised an ancient world. “Meroë: Africa’s Forgotten Empire” is being shown until 14 September at Garstang Museum of Archaeology, Liverpool. Here: A group visiting the excavations at Meroë, including (from left) Midwinter Bey, director of Sudan Railways; Lord Kitchener; General Sir Francis Reginald Wingate, Sirdar of the Egyptian Army; Professor Archibald Sayce; John Garstang; and Lady Catherine Wingate, 1911.

These kaleidoscopic images are the work of one persistent photographer’s efforts to capture vibrant hues at the exact moment a wave breaks. Ryan Pernofski‘s stunning shots feature brilliant yellows, reds, blues and purples as an array of sunlight hits the water at the perfect time. What’s even more impressive: Ryan, a 27-year-old Australian, began shooting his popular masterpieces without using a professional camera, taking his iPhone out into the water instead. Ryan began experimenting with this method in 2012, using an underwater housing to protect his phone, as he could not afford a professional camera. (Photo by Ryan Pernoski/Caters News Agency)
