The Antikythera Mechanism is sadly no longer in one piece, and the remains are fragmentary. The most significant fragments are termed the 'Major Fragments' and there are 7 of these, lettered from A to G, inclusively.

In addition to the 7 'Major Fragments' and there are also 75 'Minor Fragments' numbered sequentially. While some of these Minor Fragments definitely originate from the Antikythera Mechanism, it is possible that some of these fragments do not.
