Note 123 — THE AUXILIA DURING THE FIRST TWO CENTURIES A.D.
Reading edition
The Ala Indiana may have been called after the Trevir Iulius Indus mentioned in Tac. Ann. i. 42, the Ala Siliana after C. Silius the general of Tiberius, and the Ala Pannoniorum Tampiana after Tampius Flavianus, governor of Pannonia in 69. The last case, however, is doubted by von Domaszewski, Rangordnung, p. 122, n. 6.
