Indeed. Copyright was introduced in 1710, Principia was published in 1687.
and even with our current copyright laws providing for long dated protection, it would have still been in public domain
It's hard to say what the current laws actually imply. Steamboat Willie was originally meant to be in the public domain in 1955. Got there in 2024.
