The interface is in English. The quotations, book titles and names of scholars — the evidence itself — remain in Arabic: a translated quotation is no longer evidence.
Introduce yourself once
The Atlas is the fruit of long extraction, collation and arbitration, and we like to know who benefits from it. One introduction with a Google account — by which your email is verified rather than typed — then a few fields chosen once, and the navigation tools open to you on every visit: the merged atlas, comparison, the timeline and the index. Open without registering: the vision, the method and the limits of the data, updates — and, for anyone not registered, one record page.
Sign in with your Google account — your email is verified rather than typed:
Sign-in is by Google only, so that the email is verified and not merely typed.
The email reaches us from Google already verified — we do not ask for your password and never see it; from your account we receive only your name, your email and your picture.
This is a gate of introduction, not the guarding of an account: what is kept here is not a secret, so do not entrust to it what you would not have read.
