Rigging of roman ships

[Tib. Gabinius]

@ Tib. Gabinius: rigging = Takelage

Danke dir, ich sagte ja, mein englisch ist mies...

Ok, the velum was, if we can believe Viereck, white, and, this sounds like the connection to the vexilum, if the ship was the flaggship with the admiral on board purple or a kind of red.
I dont believe it was real purple, the costs had to be incredible...
The sipara (the little sail) was also white.
He also reports of leather strips to support the sails, so it was devided into many little squares...
