Among the clothes Ariadne is wearing in this scene is a finely woven headdress which Catullus terms a ‘mitra’ . Commentators have defined this mitra variously as a ‘scarf’ , a ‘cap or bonnet’ and a ‘kind of hairnet’ . In Greek literature, a ‘mitra’ is any piece of cloth worn by women in various ways to tie up their hair. While the word came to be used by Latin writers, it seems to have retained its specifically Greek associations. Varro (...) refers to ‘mitra’ as a Greek word: mitra et reliqua ferre in capite postea addita cum vocabulis Graecisd. (shrink)

To understand the intracellular mechanisms that control exocytosis it is necessary to have access to the cell interior. This is achieved by plasma membrane permeabilisation or by application of patch‐pipettes. These conditions permit control over the cytosol composition and also allow leakage of soluble factors that may have roles in the exocytotic mechanism. Different permeabilisation methods allow different extents of leakage and therefore provide complementary data. The exocytotic machinery itself remains intact and can be activated by providing Ca2+ and/or a (...) guanine nucleotide. In some cells there is evidence for the participation of two guanine nucleotide‐binding proteins (Gp and GE), as well as a Ca2+ ‐binding protein. In others Ca2+ is the only requirement. In a number of cell types, ATP is not required for the late steps in the secretory pathway. (shrink)
