Event for the @OCISOxford and @HSMOxford exhibition "Lines of Faith: Astronomy and the Art of the Astrolabe in the Islamic World": Joumana Medlej @joumajnouna leads a study day on Abjad numerals - Saturday 17 May. Full details at https://t.co/7dvKbnWxS2

@MichalYouDoing @joumajnouna If you're able to make it on Feb 8th, now is the time to book at https://t.co/rTtSmSlHWe. Only 3 spaces left and I'm just about to give a last promotional boost....

[Stephen Johnston @StephenHSM]

@joumajnouna Au revoir et à bientôt!

[Stephen Johnston @StephenHSM]

@joumajnouna I hadn't forgotten about the workshop/masterclass idea - would be great if it's possible - but didn't want to intrude on your creative time this term. Judging from your recent posts though, you now seem to be well and truly in the home straight.

[Stephen Johnston @StephenHSM]

@joumajnouna Happy to join the queue for the presentation too!

[Stephen Johnston @StephenHSM]

@joumajnouna @bodleianlibs When can I join the queue to order this up from Merton College Special Collections?! I know from recent experience that available slots are necessarily limited....

[Stephen Johnston @StephenHSM]

@joumajnouna Lovely - is that gold on indigo? No doubt there are quite enough brass astrolabes......

[Stephen Johnston @StephenHSM]

@joumajnouna Good news about the study day - and there are still a few places left.

[Stephen Johnston @StephenHSM]

@joumajnouna They look atmospherically celestial already - so good that they don't need to become something else?!

[Stephen Johnston @StephenHSM]

@joumajnouna Is it just me, or are there really astrolabes everywhere I look?

[Oxford Centre for Islamic Studies @OCISOxford]

@HSMOxford @OCISOxford The seminar by Taha Arslan has been postponed due to ill health. We look forward to welcoming him to @OCISOxford next term.

[Stephen Johnston @StephenHSM]

@OCISOxford Wishing Taha well for a speedy recovery, and looking forward to seeing him next term!

[Stephen Johnston @StephenHSM]

@joumajnouna @MichalYouDoing Sorry to hear that, Joumana - it would have been great to have you there!

[Stephen Johnston @StephenHSM]

@MichalYouDoing @joumajnouna Actually, you do have another chance, though for unfortunate reasons. Taha is not well so we've just rescheduled the event. It's now happening on Saturday 8 February. Wishing him all the best! The Eventbrite page is now updated at https://t.co/8zKmEM0xVk

[Stephen Johnston @StephenHSM]

@RebeccaMenmuir @mertonlib At least two outings for this astrolabe in one week - it's a mad social whirl at Merton! @joumajnouna @JuliaWalworth

[Stephen Johnston @StephenHSM]

@joumajnouna Perhaps if we were to ask @SchemeOfHeaven very VERY nicely some further adaptation might be possible? 🙂

[Stephen Johnston @StephenHSM]

@joumajnouna What sites were you using? Are you looking to generate a printout (black on white)? While you can't (currently) turn off the ecliptic, the Campanus houses or the brass colour, everything else at https://t.co/eQfSlpC9V7 can be removed, an₫ you can set your latitude.

[Stephen Johnston @StephenHSM]

@nassaujuan @joumajnouna Astrolabes and armillaries are indeed a highlight @HSMOxford, but I think Einstein's blackboard might want to have a word (not to mention original Oxford penicillin apparatus, Marconi's first public radio demonstration, Moseley's X-ray tubes.... need I go on?)

[Stephen Johnston @StephenHSM]

@MichalYouDoing @joumajnouna That's an impressively speedy realisation: I will look carefully when I'm actually awake!
