It's so excited to cosplay a Viking but they didn't actually wear horned helmets, that's a later reinvention of the imagery based on Wagnerian and Germanic 19th Century Romantic Visualisation of historic mythical characters... Just like now Vikings are all meant to have shaved sides, lots of tattoos and black inky face paint and lots of shield-maidens galore! All this fantasy external imagery has been foisted onto history by Hollywood, various fantasy artists and writers who obviously play fast and loose with the historical records and actual artefacts of the Norse culture of 1000 years ago in order to create more visually compelling warriors, explorers and tradesfolk from Scandinavia. Still this is a cat and he's doing his best....
