Domine is a slab serif typeface designed by Pablo Impallari in 2012. It was released as open-source and is freely available on Google Fonts. The design features teardrop terminals and feels almost like a cross between Clarendon and ITC Clearface. Domine was created with longform reading on the web in mind, however, it currently lacks italics so it works best as a display face or possibly for small amounts of body copy where italics might not be needed.
