Julia Smith Literal 1876 Translation:
And instantly I was in the spirit: and, behold, a throne was set in heaven, and one sitting upon the throne.

And at once I became in spirit. And, behold, a throne was set in Heaven, and One sitting on the throne.

Footnotes

10a

Instead of a dative or genitive, "sitting" is used with an accusative giving a slightly different nuance than "sitting on."

Example patterns from Homeric usage:

• καθήμενος ἐπὶ Νέστορα → “sitting toward Nestor” / “seated facing Nestor” (Il. 10.54)

• ἐπὶ Θρῃκῶν καθορώμενος αἶαν → “watching the land of the Thracians” (Il. 13.4) — here ἐπὶ + accusative signals attention / focus on.
