Thessalian and Macedonian cavalry also used non-rectangular formations. As I recall, these could be triangular or diamond/lozenge shaped, and were formed more than 4 ranks deep. I don't have the chart at hand, but I think these ran at least 8 ranks deep. Asclepiodotus' Taktika shows some diagrams of these formations. I believe they may be shown in either Conolly or Warry as well.
