The Caecilii Metelli were one of the most important families of the late Roman Republic. They rose to prominence in the beginning of the third century, with the consulship of Lucius Caecilius Metellus Denter in 284 BC. It was however Quintus Caecilius Metellus, consul in 143, who greatly improved the prestige of the family, notably thanks to his victory during the Fourth Macedonian War, for which he received the agnomen Macedonicus. His descendants and those of his younger brother Lucius received an astonishing number of magistracies during the last century of the Republic.
The overall structure of the stemma is taken from the one drawn by Münzer in the Realencyclopädie, which has recently been reproduced by Karl-J. Hölkeskamp.[1][2]T. P. Wiseman made some important corrections in two articles on the descendants of Balearicus and the later Metelli, which have been included.[3]
The nomen Caecilius is omitted for all the men named Metellus. All dates are BC, except stated otherwise. Numbers in brackets indicates the order of marriages. Dotted lines show adoptions.
