The sun hung low over Mystras, gilding the fortress walls and winding streets in a final burst of warm light. From the palace the town fell away down the slope, to the plain of the Eurotas going grey with evening. The bells of Agios Demetrios had rung vespers and fallen silent. Lower on the hillside, half built into the rock, the lamps of the Peribleptos were being lit.
In one of the castle's private chambers, Theodore Palaiologos stood by a narrow window and watched the hills beyond the city darken.
A soft knock interrupted his thoughts. A servant appeared, bowing.
"Master Plethon awaits you, my lord."
Theodore's gaze lingered on the horizon a moment longer before he turned, jaw set. "Let him in."
The door opened to admit Georgios Gemistos Plethon, nearly seventy now, his long beard streaked with white, his robes plain and unadorned.
"Theodore." Plethon nodded.
"Plethon." He gestured toward the chair by the modest hearth. "Sit. Will you take wine?"
"A little." Plethon lowered himself into the chair.
A jug stood on the sideboard. Theodore poured, and set the cup at his elbow.
"Mild winter," he said.
"It is."
"Your students keep you busy?"
"They do." Plethon folded his hands and waited.
The fire cracked.
"You did not call me here after vespers to talk about the weather, Theodore."
"No. You asked me for a schoolhouse. A roof of your own."
"I did. In the autumn."
"I have been through the numbers with the treasurer twice. I cannot give it to you this year. The walls need work and the garrison needs pay."
"The Metropolitan preached against me again on Sunday. At Agios Demetrios. I am told the cathedral was full."
"The new Metropolitan is zealous. It will pass." Theodore looked at the hearth rather than at him. "Until it does, it might be wise to keep your teaching within your own walls. The dinners. Your circle. Men he cannot count from his cathedral steps."
Plethon looked at his folded hands. "A smaller room each year."
"I do not command it."
"No. You advise it." The old man smoothed his robe. "I taught you in the Palace of the Despots when you were a boy. Now you counsel me to teach from my own courtyard."
"I remember the lessons." Theodore turned to the window. For a while neither of them spoke.
"Was there something else?" Plethon said.
Theodore kept his eyes on the dark hills.
"You wore that same look when a lesson had gone unlearned and you did not want to say so."
Theodore turned from the window. "You have my brother's ear in these negotiations with Rome. Tell me plainly. Do you believe in this compromise? Would you have us bend the knee to the Latin Church?"
"I do not suggest compromise lightly. But the emperor believes union may buy Western aid, and without Western aid the Ottomans will finish us. I cannot dismiss that out of hand."
"The Latins sacked the City once already. Desecrated our altars. And now we are to trust the West to respect our traditions?"
"I have not forgotten. The scars of those days remain with us all. But the Ottomans take another town every year. If the empire falls, what becomes of the faith then?"
"And what has Latin protection bought Thessaloniki? Andronikos sold the city to Venice and now prays in a monastery in Constantinople. The Turk sits before its walls all the same, and Venetian banners will not stop him. That is the worth of the West."
"That is the worth of half-measures. A city pawned to one republic is not an alliance. The emperor means to bring the whole of the West in at once."
Theodore moved to a small table where a candle burned before an icon of the Virgin. He traced its edge with one fingertip. "This is not a diplomatic turn. It is the creed itself. The filioque. Papal supremacy. Everything we have withstood, now to be accepted as a tactic."
Plethon tilted his head. "Then bind them to terms. Fealty on paper, and in exchange the rites stay untouched, written into the act itself."
Theodore's voice grew taut. "You speak of negotiation. I fear the Latins speak of conquest. Their appetite for dominion has not changed since they first set eyes on Constantinople."
For a moment, Plethon did not reply. "I have spent my life sifting through the wisdom of Plato and the old Hellenic sages. I have seen how an empire can crumble when it clings too tightly to old forms while the world transforms around it. We are at a crossroads, Theodore, one requiring creativity as much as faith."
Theodore turned abruptly, as though the philosopher's words struck a nerve. "We do not need to forsake our faith to adapt. There are reforms to be made, yes, but not this union. Would you have us part our lips in prayer to the Pope?"
"I am no Latin apologist, Theodore. If the liturgies can be kept, I would keep them. But I would keep the empire around them too."
Theodore dropped into a chair and pressed a hand against his brow. "My father held that the faith was the last bulwark against chaos. I hear his voice still, telling me to hold the line, whatever it costs."
A hush fell. At length Plethon spoke. "You call me a radical because I read Plato. Well. Plato taught that a ruler must sometimes lead his people where they do not wish to go. Your father understood that better than most."
Theodore laughed, short and without humor. "There it is. An empire rebuilt on your Hellenic notions. The people cry out to the Virgin and the saints, not to Plato's republic. They would call it heresy, and they would not be far wrong."
Plethon spread his hands. "I know my reputation. I do not preach the old gods. I read our ancestors for what they knew of governance and law, knowledge older than these schisms. That is not tearing down the church."
Silence settled. Theodore looked at the icon, the candle's glow moving on the Virgin's face.
At last, Theodore spoke, a weary resignation in his voice.
"You would have me consider forging an alliance with the West, rethinking the role of Hellenic learning in our realm, all to stave off the Ottomans. I wonder if you see how precarious such steps could be. No matter how we frame it, many will call it betrayal."
Plethon rose. "Leadership demands more than pleasing the multitude. You may yet find a middle path, one that spares Orthodoxy from corruption while securing the alliances we need. It is not an easy route, but it is there for those who dare to seek it."
Theodore closed his eyes briefly, letting out a long sigh. "Your words carry both promise and risk, Plethon. And still, you know the church elders will not bow to such bold reforms without a fight."
"There will always be a fight," Plethon said softly. "Better that it be on our terms."
He inclined his head in a final show of respect and stepped toward the door. Theodore watched him go, then called after him, voice echoing in the dim corridor:
"Old friend. If there is a way to secure the empire without forsaking our soul, I would hear of it."
Plethon halted, glancing back. A gentle smile touched his lips, fleeting as candlelight. "That is all I ask. May reason and faith both guide you, Theodore." Then he disappeared down the corridor, his footsteps fading into the hush of the castle.
Left alone, Theodore returned to the window. Night had fallen, and the hills were gone into the dark. He placed a hand on the cool stone, recalling Plethon's fervent talk of a renewed Hellenic glory, a concept so radical that it unsettled him as much as the threat from the Ottomans themselves.
His gaze dropped to the icon of the Virgin. The candle before it had burned low. He took up the snuffer, held it a moment, then set it down and trimmed the wick instead, until the flame stood steady.
He was still at the window when the watch changed below.
