Books and Reference Books

Omega Forums is pretty rich in posts about Omega and other brand reference books, but I can’t help but wonder if a thread that is a kind of a book clearing house might not be helpful.

When I was looking for a thread featuring general horology books I came across a post by chipsotoole at https://omegaforums.net/threads/antique-watch-horology-books.126176/ who was describing some of his more interesting finds at a small auction house: a fake Rolex, and some 18th century horology titles. But, alas, that post was a singleton. I looked at the profile and saw it had been inactive since 2022. Does anyone know in real life if Mr. Chipsotoole still with us?

Picture of the frontispiece and an interior page spread of a 16th century book for funsies.

Apologies for the poor photograph of the book pages. I need to retake a bunch of book pictures with two things--a camera stand and a proper camera.

Meanwhile, here is the title and the translation of the title and the publication information. Using the online Latin translation, the best I can guess is that this is about "sector clocks."
=========
Conformatio Horologiorvm Sciotericorvm In Svperficiebvs Planis Vtcvnqve sitis, iacentibus, erectis, reclineatis, inclinatis, & quocunq[ue] spectantibus, compendiaria & facilis : Cum Quadrantis Horologici & Geometrici conformatione & vsibvs, ac Tabulis Sinuum

Hermanni VVitekindi
==========
Arrangement of sector clocks on flat surfaces, however, it is located, lying, erect, reclined, and inclined and from whatever angle you look at it, it is concise & simple

With the configurations of Horological & Geometric Quadrants & uses, and the Tables of Sines

By Hermann Witekind. Published in Heidelberg by Harnisch in 1576. Printed by Meyer in Heidelberg. 60 pages

Does this fit with anything anyone knows about "sector" clocks? Or might the translation guess be altogether mistaken?
