The Great Translation

At its broadest, "the Renaissance" IRL means the economic and political upheaval caused by the Black Death and the end of the Medieval Warm Period, the changing power dynamics between Rome and the kingdoms caused by the Avignon Schism, linguistic changes caused by the rise of vernaculars and the rediscovery of classics (beginning with the Greek texts brought home from the Latin Empire, and accelerated as Byzantine civilization declined in its aftermath.)

And that's a problem for me. Because there's no guarantee that the Fourth Crusade (and there will be a Fourth Crusade) will result in the Latin Empire; there's no guarantee that church-state power dynamics will change because there may not be an Avignon Papacy; the Black Death could very well evolve in a different way. (Vernaculars and the end of the Medieval Warm Period, well, there's only so much that can be done about those.) Between that and a generally different intellectual landscape, there's no reason to think that the 13th century is going to play the same way, or indeed that it's going to be called "the Renaissance."

There is, however, going to be the Great Translation

Luciferianism and the Black Death

Moorish Spain has a rather occult modernity.

IRL, there was a Hermetic Reformation in the early 1500s: Pico della Mirandola, Giordano Bruno, Paracelsus, and a few others that come to mind. It didn't go anywhere really big in Europe, for the perfectly valid reason that Europe at the time was having a much bigger shakeup in the form of the Protestant Reformation. Seville, however, isn't going to have that kind of shakeup. I don't see any new madhhab arising from its Malikism (although maybe a few tariqas from its late Sufism?) Everything about the flow of history points to the fact that the world-shaking events of the 1500s are simply going to reinforce their attitudes of (Maliki, Moorish) Islam as universal empire.

In that context, seizing on Bruno and della Mirandola would be a way to shake things up, emphasizing that Moorish Islam is a very different beast from the Turkish juggernaut that dominates the rest of Islamic Eurasia - and letting them enter modernity as the weird uncle of Europe rather than having modernity happen to them.

The problem is historiography.

Things don't just happen. In most universes, people assume that the way things happened for them are the only way it could have. They also perceive this as part of a continuity of progression from the past, especially with something (like Hermeticism) that draws its authority from its antiquity. Andalusada is going to write its own history, and given Moorish Hermeticism, they're going to wonder "Where was the occultism that Moorish Hermeticism came from in the past?"

I have an idea. It involves the Black Death.

The Guerillas of Toleto

The survival of Moorish Spain (in the form of Seville) effectively stalls the southern expansion of the Roman Rite. Under various iterations of Moorish rule, the Mozarabic liturgy survives long past the point where it died out IRL.

It also means that the struggle within the Spanish Church over which Rite to use is more pronounced, and much more politicized, because the major players - Aragon and Catalonia - are extremely tied to the Roman Rite. Their efforts to push south (and not purely military ones; witness the Gonzalans) are going to be resented, and perceived as imperialism, by the Christians living under Moorish rule.

This most frequently comes to a head in the Primate of Spain: Toleto, a city (like Batallos) on the edge of both the Christian and Moorish worlds, and (unlike Batallos) one that changes hands at least twice during the Middle Ages. [details?] In Milan, attempts to suppress the Ambrosian Rite led to repeated riots. Attempts to do the same in Toledo are going to lead to what are called, in hindsight, the guerillas: the little wars.
