The actor portraying Dante, Adrian Paul, has been in two other productions with Dante in the title. Dante's Hell Animated (2013) and Dante's Inferno (2024).
The symbol on the sword belonging to Dante was described as "it dates back to the 1400's" - which does not make any sense. This type of sword is based more in the 9th and 10th century and is located in the Scandinavian (Viking) region. So marking a ~400 year old sword with a strange symbol is nothing that would have been done in the late middle ages.
