You're referring to the Lateen sail that appeared in the eastern Mediterranean as early as 100AD, but it was imported from possibly Egypt or the Persian Gulf, so its origin is older and elusive. But the spritsail can also sail upwind and is far older, only appearing in Greco-Roman navigation in the 2nd century BC.
