Sequoia and the tulip-tree still remain; figs are abundant; laurels are represented by Sassafras and camphor; herbaceous plants (Ranunculaceae, Cruciferae, Umbelliferae) are present, though, as might be expected, only fragmentarily preserved.
In Italy the signs and works survive fragmentarily in the baptistery at Parma, completely on the porch of the cathedral of Cremona and on the west doorway of St Mark's at Venice.
Unfortunately this great work proved too voluminous to be preserved entire; and in the form in which it was fragmentarily preserved, it even largely enhanced the critical task of later centuries.
