Castra Alata
Castra Alata in Britain. This is the rendering of the Πτερωτὸν στρατόπεδον of Ptolemy. It is twice mentioned by this author (2.3.13, 8.3.9), and by him only; once as having its longest day of 18 hours, and one-half,
and being distant from Alexandria to the westward 2 hours and one-sixth;
and again, as being, along with Banatia, Tameia, and Tuaesis, one of the four towns of the Vacomagi,--these lying north of the Caledonians, and north-east of the Venicontes. It has been variously identified, viz. with Tayne in Ross, with Burghead in Murray, and with Edinburg. None of these are certain.
