E.g. Tartarus instead of Tartaros, Daedalus instead of Daidalos, Cerberus instead of Kerberos, Cassandra instead of Kassandra… There are a lot of these names that are more widely used in their Romanized forms. Yet if we talk about mythological names instead the Greek names are more widely used (althrough this was different over 200 years ago)
Because the Roman’s are the ones who conquered Europe so their standards and customs got passed along.
There’s a video of an Indian comic explaining why Shakespeare is considered the greatest writer ever.
One part of it is the English conquering 75% of the planet and putting their teachers in every classroom.
You have not experienced Shakespeare until you have read him in the original Klingon.
If you have that available to post it sounds like an interesting watch.
