‘Do you know the Epitome of Ptolemy’s Almagest?’ he asked her, resting the book open in his lap.

Luna shifted in her seat.

When she didn’t speak, he pushed a little further. ‘Most students of astronomy know this work of Joannes de Monte Regio—or Regiomontanus, as he likes to be known. I myself have read it twice, at least. I thought perhaps you’d studied it?’

‘What makes you think that?’

‘You told me you were at the professor’s talk, at Villa Rucellai.’ He flashed her a tentative smile. ‘Then I remembered what your father did to you. Don’t be ashamed; it was a very difficult situation for a girl to be put in, tricking everyone like that. Your father should have known better.’

Luna raised her chin. ‘Are you interested in discussing Ptolemy with me or the gossip of my attendance?’

He flinched at her angry tone.

‘Forgive me,’ she said. ‘I am still so ashamed …’

Silence fell between them. It was impossible to fully explain how deeply her shame ran, but then she saw the way he looked at her, without judgement or blame but rather with the same offer of comfort that Elisabetta’s friendship had given her, and she wanted him to understand.

‘My father would prime me with a pointed comment then sit back with his friends and watch as I performed. His daughter, the curiosity. Oh, I spoke eloquently and at length and I did so willingly because I enjoyed the attention—nay, I revelled in it. I thought I was special.’ She reached across to tuck the coverlet more tightly about the sleeping lady’s shoulders. ‘I was arrogant and needy as they all said I was.’

‘You speak truthfully and that is a strength; if you were that person you describe then know that she is not who you are today.’

Nicolaus got up and stretched his back. ‘I would stay longer but the professor insists on my attendance in his rooms each night as we prepare for the lunar eclipse tomorrow eve.’ He hesitated. ‘I would welcome your company to view the eclipse.’

She saw acceptance in his chestnut eyes. Still she could not say yes and stayed in the chair as he bowed and then left. Luna listened to the sound of his footsteps retreating down the stairs. She sat and watched Elisabetta sleep. Her face had a healthy colour and her breath was slow and easy. She’d be fully recovered soon enough.

Elisabetta stirred and Luna helped her to sit up.

‘I’m thirsty.’

Luna passed her a mug of wine. ‘I am glad to see a healthy colour has returned to your cheeks, mistress.’

‘Thank you, Luna. You are so kind. It was our good fortune God sent you to us when He did.’ Elisabetta took hold of her hands and Luna felt her strengthened grasp as she clasped them to her breast. ‘You have been like a daughter these last months.’
