What is the mechanism of the fluorescein synthesis performed by von Baeyer?

In order to get the form of the molecule shown as the product of your reaction, the $$\mathrm{pH}$$ needs to be increased in order to open the lactone ring.(3) This is fluorescein-A, the form of the molecule that actually fluoresces.
