about 「Handy table」by Ptolemaios

[februs]

There are many copies of the so-called handy tables, but it is only this manuscript (Vat.Gr.1291, in the Vatican library) that has this particular illustration.

It is long ago that I looked at this, and I have some vague memories of what I read about it, which is probably not reliable.

Please note that Nick Pelling also wrote about it in 2017:

the site explains that the pic is 「 A beautifully illustrated copy of Ptolemy’s Handy Tables」.

so is the pic handy table, isn't it? (@_@)
