“…Nevertheless, we decided to analyse samples from the recent excavations for analysis, using high-performance liquid chromatography (HPLC). HPLC is a considerably more advanced method, which can distinguish dominant and minor components in the sample, and determine with a high probability the species of murex that was used (for similar studies, see Koren 2008a;Sukenik et al 2015).'True purple', according to the accepted view in research, was extracted from a number of species of the Muricidae family, and in particular from three species that were common in the Mediterranean: banded dye-murex (Hexaplex trunculus L. = Murex trunculus), spiny dye-murex (Bolinus brandaris L. = Murex brandaris) and red-mouthed rock shell (Stramonita haemastoma L. = Thais haemastoma, which is nowadays classified as Rapaninae-for further discussion, see Spanier and Karmon 1987, 180-2; Cardon 2007, 566-86;Reese 2010). The dye that was produced from the murex sea snail was considered as the most prestigious dye for textiles in antiquity.…”
