Brought from Rome by Juan Navarra in 1575 & presented to Toledo Cathedral. Contents are all alternative redactions - possibly designed for a Spanish audience - of works featured in Victoria's 'Liber primus' (1576). "The largest and probably also most important of all Victoria manuscripts" (Noone/Skinner), it shows very little sign of any use.

Copied by the papal scribe Johannes Parvus (Brauner 1988), perhaps at Victoria's own instigation (it is the first copy of any of Victoria's music by Parvus & pre-dates the arrival of Victoria's works in the papal chapel's repertory). It has also the largest page-size known among the Parvus mss. The Magnificat settings are arranged in odd/even sets, unlike mss for the Papal chapel, arguing that Parvus did not produce this for the Vatican.

Boards with leather covers, adorned with ten studs, corner-pieces & brass clasps

Two crossed arrows under a six-pointed star. I-Rvat SMM 29 & I-Ls A.8 share same paper size & watermark - dated after 1576 & before Oct 1577 by Brauner, though Noone/Skinner argues for an earlier date.

Dated c1577 by Wojcicka-Hruza; Thomas Schmidt suggested a period of compilation between the middle of the decade of 1560 to the beginning of the 1570s (NooneFuentes); 1572-75 (Noone/Skinner).

a single illuminated set of arms (of Juan Navarra) was at the beginning, but was removed sometime after 1795. Other colour illuminations added at Toledo Cathedral after the ms was donated.
