Marci's letters to Kircher, revisited

[Kestrel]

Hmmm,

the difference of meaning between sch(a)edula and schaedata doesn't seem fundamental to me.
Barschius submitted *something* and it would have been something drawn or written on paper.

I certainly wouldn't claim that there are any earth-shattering disclosures involved here. However, the schaedata reading poses a problem precisely because it is not a real Latin word. If Marci wrote an unknown word like schaedata in this connection then we would want to know why; and the nature of the attachment would always be open to question.

If the correct reading is schedula - a perfectly normal Latin word, with a dictionary definition - then a perceived element of strangeness vanishes. It also means we can rule out anything sizeable (like a multi-paged booklet, etc.) as the attachment.
