a, Representative CT slice of fragment B, showing part of the Metonic dial. The scales are 7 mm wide and the text 1.7 mm high (Supplementary Notes 3). b, Text in red was traced from the CT—just enough being deciphered to discover all the month names; text in blue is reconstructed (colouring in d follows this convention). The months here are
KPANEIO
, 
ANOTPO
IO, MAXANE
and
EKATE. c, CT slice through fragment B, showing the Olympiad
dial. L and NEMEA can be seen faintly on the left-hand side. d, The four
sectors of the Olympiad dial are labelled LA, LB, L
and L—years 1, 2, 3
and 4. Outside are the Panhellenic Games: year 1: I
MIA, OIA;
year 2: NEMEA, NAA; year 3: IMIA, IA; and year 4: NEMEA,
and undeciphered text. To the right of the dial are the numbers 
(6) and IA
(11) for the excluded days.
