Suggestions for old literature or poetry on medieval fantasy/romance?

After researching old translations of The Arabian Nights, I discovered a poet called John Payne, who lived 23 August 1842 – 11 February 1916:

I delved into some of his narrative poetry, of which he occasionally used medieval or mythological subjects. Here are two small examples of his 'The Building of the Dream' from 'The Masque of Shadows' - a poem about a knight who uses a magic scroll to enter a dream of his bygone youth:

I found his colourful imagery and poetry truly beautiful. If possible, I would like to read other 19th to early 20th-century works that explore medieval themes (knights, palaces, dragons, romantic sonnets, etc.) in a similar style.

Any recommendations would be warmly appreciated. Thanks for reading. *Air hugs.*

Note: I also posted this in another group. I hope that is okay.

The obvious one is Tennyson’s Idylls of the king, but you probably know those already. Maybe the recommendations from there would help you?

Some other possibilities might be:
Tennyson, Lady of Shalott Loreena McKennitt sings a somewhat revised version of this poem. One version is here: https://youtu.be/80-kp6RDl94
Keats, La Belle Dame Sans Merci
Browning, Childe Roland to the Dark Tower Came
Rossetti, Goblin Market

It might also be interesting to look at the work of James Macpherson (Ossian) and Thomas Chatterton. These "frauds" had a big effect on the aforementioned writers.

La Chanson de Roland Song of Roland has all the heraldry, chivalry, and poesy I think you're looking for. Authorship buried in the sands of time. Turoldus' authorship is speculative IMHO.
