The first owner of the manuscript was an Italian humanist,
Coluccio Salutati. In the mid-16th century
Achilles Statius, in his edition of Catullan poems, shows an acquaintance with this codex. Later the codex was lost: it was probably housed in the
Vatican Library for a very long time, hidden under a false catalogue number, until it was rediscovered in 1896 by
William Gardner Hale. Hale promised to collate the codex, but failed to do so before his death in 1928 – this in turn delayed the now general acceptance of R as one of the first rank Catullian codices. The codex was collated by a Canadian scholar, D. F. S. Thomson, in 1970. == See also ==
