The "Fred thread": the Argead Macedonian Army

[Paralus]

see for example this newspaper report:-
Macedonian warriors lying at eternal rest for more than 2,500 years in the ancient graveyard at Archontiko, Pella, have
kept secret both their gold and the Greek character of Macedonia.

One would dearly love an archaeological report rather than a newspaper report that proceeds from the assumption that this proves the "Greek character" of ancient Macedonia.

It is possible that both cavalry and infantry equipment is depicted of course - consider both found in the 'Philip' and other tombs, and of course wealthy aristocrats could and probably did possess more than one helmet c.f. for example Italian tombs showing multiple 'panoplia'

To quote J. K. Anderson:

Most important of all is the frieze from the monument of Aemilius Paullus at Delphi. This has been convincingly interpreted as showing actual incidents of the Battle of Pydna on 22 June 168 B.c., and it includes three examples of "Macedonian" shields whose embossed decoration is very similar to that on the south wall of the Tomb of Lyson and Kallikles. These are all carried by infantrymen, which removes the temptation to argue that the occupants of this rich sepulcher might have served in the cavalry.
