Apparently named after this unprepossessing concoction, tetrafarmacum (standard Latin tetrapharmacum) was a complicated and expensive dish in Roman Imperial cuisine. It contained sow's udder, pheasant, wild boar and ham in pastry. The only surviving source of information on the tetrafarmacum is the Historia Augusta, which mentions it three times. All three mentions are credited to the now-lost biography of Hadrian by Marius Maximus. According to this source, the Caesar Aelius Verus (died 138) invented the dish; his senior colleague, the Emperor Hadrian, liked it; a later emperor, Alexander Severus, liked it too.
