The question about who wrote Grettis saga has been debated among academics for decades. It was Sigurður Nordal who proposed that it was Sturla Þórðarsson (214-1284) that wrote the orginal version. This book contains studies into this theory and even uses computer science to compare texts and solve this puzzle once and for all.
