This paper sets out to explore the possibility of detecting references to time notation expressed in a semasiographic fashion in the Linear A and Linear B ideogram for wine: AB 131/VIN(um). This sign occurs in three variants, namely AB 131a, AB 131b and A 131c, with the latter variant being attested only in Linear A. Evidence will be put forward to argue that graphic alteration of the form of the main sign (AB 131a) was used as a method to give rise to variants of the sign (AB 131b, A 131c) meant to convey chronological information in a semasiographic way, i.e. without recourse to phonetic writing.
