Dear Prof. Slaje,_______________________________________________
Many thanks for your reply to my message on the radiocarbon dating of the Bakhshali manuscript, I was hoping to read your comments and opinions on the results. I feel that I have to clarify some points and I hope that this reply will help you at least a little bit to dissipate some of your legitimate doubts. I also hope that you will forgive me if I might sound a bit on the defensive, but I have spent the last months doubting myself the results of the radiocarbon dating, only to have to slowly revise my opinions and be more open to possibilities.
I have greatly profited from your wonderful 1993 book on the Śāradā script when I was still a PhD student working on Kashmirian manuscripts, then when I was I cataloguing the Śāradā manuscripts in the Cambridge collections, and more recently when I was completing a survey of the birch-bark manuscripts in the Bodleian collections to assess their conditions (I was surprised to find five uncatalogued birch-bark manuscripts belonging to what I call the Leitner collection, which are actually mentioned in the introduction of the catalogue by Winternitz and Keith, but that had escaped my attention so far; anyway, this is yet another story). I am fully aware that I am a beginner in the field of the paleography of the Śāradā script. Moreover, I know very well that I am certainly not the most qualified scholar who could assess the implications of these results for the palaeography of North Indian scripts, and certainly not at all for the history of Indian mathematics. Nevertheless, I have been asked to assist during the whole project of radiocarbon dating the Bakhshali manuscript in my role as the curator of the Sanskrit manuscripts in the Bodleian Libraries. I have tried to do my best and to do my homework properly, so to say, if you allow me this rather prosaic simile with the job of school students. I have taken care of all Indological aspects and implications of this project very closely since its outset. In our team we are all well aware of Takao Hayashi's work on the Bakhshali, in fact we have been in contact with him and Agathe Keller before the start of the project, and the only reason why we haven't communicated the results to them in advance and before the press release is because of decisions coming from higher above us in the food chain (if you allow me again a prosaic metaphor). In fact, I have read and used Hayashi's 1995 edition very intensively in the last few months, alongside Kaye's first edition, Hoernle's article, and several other articles and books on the topic of zero and the history of mathematics in India (many thanks to Kim Plofker, without her wonderful contributions to the history of Indian mathematics I would have been lost), as well as Lore Sander's palaeographical studies, your own 1993 book, and several other publications on the palaeography of Indian scripts (obviously starting with the one by our great forefather Georg Buehler). The reason why Hayashi is not mentioned in the Guardian article–nor is any of us from the team, by the way, except for Prof. du Sautoy–is that this is an article in a newspaper and hence written for the broader public. As one of my Bodleian colleagues pointed out to me today when I wrote to him that I was disappointed that none of us from the team was even mentioned in the Guardian article (above all because two of us are EU citizens, and I believe I don't need to say more): we cannot control what the press chooses to do and publish. The Guardian was allowed the exclusive on this news (together with the BBC) and provided with the names of all members of the team that I mentioned in my first message. They chose to interview and quote only Prof. du Sautoy and the Bodley's Librarian Richard Ovenden, who both have a high profile and an own Wikipedia page. If this is what Bodleian Communications thinks it's better to do to have a wider impact on the broader public, well I can't certainly influence their decision. I surely agree with you that it would have made a hell of a lot more sense to interview Takao Hayashi and ask him his opinion, but we all know how these things go, don't we?
Finally, I am well aware of the existence of INDOSKRIPT and I have used this wonderful tool before, but I am sorry to say that at the moment I do not fully agree with the statement "The individual akṣaras of the Bakshāli MS can be consulted in their extracted forms and [...] compared to their paleographic environment most conveniently [italics mine] by using the tools of INDOSKRIPT." The reason why I do not agree is merely a technical one. I used to consult INDOSKRIPT regularly when I was running a PC with Windows XP. When I switched to Linux/Ubuntu I then installed a pirate copy of Windows XP on a Virtual Machine only to be able to use INDOSKRIPT (this was back in 2007). Soon it turned out to be too taxing for the RAM of my computer and also it was pretty cumbersome to switch from Ubuntu, on which I was running Emacs for my work, to the VM to consult the INDOSKRIPT database. When in 2011 in Cambridge I was given as project laptop a MacPro, again I tried to install INDOSKRIPT, this time using the Wine emulator program. Much to my dismay, this time INDOSKRIPT didn't start at all. I did not want to install again a VM and install on it a Windows system, because I did not have access to any pirate copy of Windows XP (probably I could have easily downloaded one, I know) and I did not want to buy Windows only to run INDOSKRIPT. I have just followed the link to the INDOSKRIPT webpage that you provide and I cannot find any further implementation of the INDOSKRIPT database to run it on a Linux or Mac OS X system. If I am missing it, I kindly ask you to point me to it, as I certainly do not want to reinvent the wheel and if I can easily install this wonderful database on my Mac OS X or my Lubuntu machine to comfortably compare the akṣaras of the Bakhshali manuscript, I will do it for sure, instead of slaving to extract and modify akṣaras from the pictures of the Bakhshali I have or from images of manuscripts I have downloaded from the IDP website.
(As a side note, I actually prefer to use the facsimile in Kaye's edition, since we are not allowed to photograph the Bakhshali anymore due to its poor condition and I have been told that when Hayashi asked permission to use in his own edition the reproductions used for Kaye's edition, it turned out that the original takes got lost, so the facsimile in Hayashi's edition is based on photographs of the printed version of Kaye's facsimile.)

Subject: Re: [INDOLOGY] Once again on the origin of zero: the date of the Bakhshali manuscript (or manuscripts?)I fully concur with what Dr Acri has to say in this matter. Moreover, the initial statement of the interviewed mathematician „The most exciting thing is that we’ve identified a zero“ is presumptuous, as the „identification“ claimed here is actually decade-long common Indological knowledge easily traceable in the relevant literature on the subject. I wonder why no Indologist with a profound disciplinary knowledge was asked to give qualified statements.
A reproduction together with a transliteration of this famous manuscript was brought to the public in 1995:Takao Hayashi, The Bakshali Manuscript. Groningen 1995.
The individual akṣaras of the Bakshāli MS can be consulted in their extracted forms and, in the possible attempt of a fresh dating, compared to their paleographic environment most conveniently by using the tools of INDOSKRIPT (http://userpage.fu-berlin.de/falk/):

Vindobonae, die XXI. mensis Novembris MCMLXXXIII.2017-09-15 2:41 GMT+02:00 Andrea Acri via INDOLOGY <indology@list.indology.info>:Dear Camillothank you for sharing this news, and especially for your (in)valuable work on this most important document. Let me point out at the very outset that all I know about this manuscript derives from the Guardian article and Wikipedia (disclaimer: I have no access to a library right now!), so please forgive me for being so naive.If the manuscript (however fragmentary it may be) is thought to contain a single, unitary text, then the date of its copying (and/or composition?) must be the 9th-10th century. I fail to see what is so sensational about this apart from the fact that it shows how writing supports that were centuries older might have been (re)utilized. (By the way: is an analysis of the ink technically possible?). The earliest attestation of the written zero would still be the 8th-century Southeast Asian inscriptions (and not the Gwalior temple, as incorrectly reported in the article).But in your message, when you speak about different stratas and tables of ak.saras, you clearly imply that this/these manuscript(s) contain(s) a composite/heterogeneous text indeed, and that part of it might date back to the 3rd-4th century. May I ask you to anticipate/synthesize some of your key findings here, or at least clarify this point? And, what is the relationship between folios 16 and 17? Do all these folios contain the 0?Further: I'm not steeped in mathematics either, so I fail to grasp the full implications of this statement (especially the second sentence):"In the fragile document, zero does not yet feature as a number in its own right, but as a placeholder in a number system, just as the “0” in “101” indicates no tens. It features a problem to which the answer is zero, but here the answer is left blank".Hopefully some of our learned colleagues will be able to clarify this point.Best regardsAndrea AcriSent from my iPhoneDear Colleagues,I’m pleased to be finally able to share this exciting news with you:I imagine that some of you might probably raise their eyebrows after reading this article. The results came as a big surprise to us too, and to me were literally jaw-dropping. I realize that these results have several implications not only for the history of mathematics, but also for our field of study, and I know that the article in The Guardian surely doesn’t answer the many questions you might be asking yourselves now. I will try to briefly anticipate some of them.The decision and implementation of radiocarbon dating the Bakhshali manuscript took several months of preparation on the part of the team of colleagues with which I collaborated. The team included colleagues from the Bodleian Libraries and other University of Oxford departments: David Howell (Bodleian Libraries’ Head of Heritage Science), Dr Gillian Evison (Head of the Bodleian Libraries' Oriental Section & Indian Institute Librarian), Virginia M Lladó-Buisán (Bodleian Libraries’ Head of Conservation and Collection Care), Dr David Chivall (Chemistry Laboratory Manager at the School of Archaeology of the University of Oxford), and Prof. Marcus du Sautoy (Charles Simonyi Professor for the Public Understanding of Science and Professor of Mathematics at the Oxford University). We decided to take samples from three folios in order to be sure to have a sensible margin of certainty for the results. I chose folios 16, 17, and 33, and the analysis was conducted by Dr Chivall at the Oxford Radiocarbon Accelerator Unit. The results of the calibrated age (95.4% confidence interval / cal AD) are as follows:Folio 16: 224 (95.4%) 383calADFolio 17: 680 (74.8%) 779calAD790 (20.6%) 868calADFolio 33: 885 (95.4%) 993calADWe did not expect such a big difference in the date range of the three folios. I am currently preparing an article in which I provide the background for the choice of these three specific folios, tables of all akṣaras from the three folios as an aid to assign the extant folios to the different strata of the manuscript (including selected aksaras of other dated and undated manuscripts in similar scripts for comparison), and a first palaeographical appraisal of the results.Best wishes,CamilloDr Camillo A.
