ARMILUSTRIUM
an open space on the north-western part of the Aventine,
probably just south of the present church of S. Sabina, where the
annual festival of the Armilustrium was celebrated on 19th October.
Titus Tatius was said to have been buried here (Plut. Rom. 23). The
vicus Armilustri (
CIL vi. 802, 975, 31069; Bull. d.
Inst. 1870, 88) probably
passed through it, and may have followed the line of the modern Via
di S. Sabina (Varro,
LL v. 153;
vi. 22;
Liv. xxvii. 37. 4; Fest. 19;
Not. Reg. XIII; CIL i 2. p. 333; HJ 161-2; Merlin, 313-315).
