Is the Phaistos disc in family with the inventory item no.2646 from the Heraklion Museum 'the Chronos' disc', which contains four coils with 62+38+24+16=140 (button) holes, against the P.D.'s part A, which dissolved in multipla of 5.5, gives 61+38+22+16=137 units ? Quite a question!
NB. The item 2646 is not confirmed as being a calendar anywhere else on the internet. - It might as well be an old strainer. Definitely not a linguistic sieve!
