In 398 BC, Medullinus was elected Consular Tribune for the third time, alongside
Lucius Valerius Potitus,
Marcus Valerius Lactucinus Maximus,
Quintus Servilius Fidenas, his famed brother,
Marcus Furius Camillus and
Quintus Sulpicius Camerinus Cornutus. Medullinus and some of his colleagues continued with the siege of Veii, while Valerius Potitus and Medullinus' brother Furius Camillus sacked the towns of
Falerii and
Capena, which were allied with the Etruscans. During this year there was also the unusual rise of the waters of
Lake Albano, and to interpret the meaning of which some ambassadors were sent to question the
Oracle at Delphi, even though an old prophet from Veii had let slip the following prediction: that whenever the water of the Alban Lake overflowed and the Romans drew it off in the appointed way, the victory over the Veientines would be granted them; until that happened the gods would not desert the walls of Veii. Then he explained the prescribed mode of drawing off the water. In the following year (397 BC), Medullinus was elected Consular Tribune for the fourth time, alongside
Lucius Julius Iulus,
Aulus Postumius Albinus Regillensis,
Publius Cornelius Maluginensis,
Lucius Sergius Fidenas and
Aulus Manlius Vulso Capitolinus. This year saw Medullinus and his colleagues continue the siege of
Veii, while at the same time having to endure an attack by the
Volsci on the garrison at
Anxur, as well as an attack by the
Aequi on the colony of
Labico. Into this already difficult military situation, the Romans were further placed under pressure by raids from
Tarquinii, who tried to take advantage of the situation, confident that the Romans would be unable to launch any reprisals. Instead, a force was raised by Postumius Aulus and Lucius Julius, who surprised the raiders at
Caere, and proceeded to annex the town from the
Etruscans. The ambassadors which had been sent to question the Oracle at Delphi returned with the following response: See to it, Roman, that the rising flood At Alba flow not o'er its banks and shape Its channel seawards. Harmless through thy fields Shalt thou disperse it, scattered into rills. Then fiercely press upon thy foeman's walls, For now the Fates have given thee victory. That city which long years thou hast besieged Shall now be thine. And when the war hath end, Do thou, the victor, bear an ample gift Into my temple, and the ancestral rites Now in disuse, see that thou celebrate Anew with all their wonted pomp. Due to faulty elections, it was decided that the necessary act to restore the neglected rites involved the abdication of all the consular tribunes from their office for the remainder of their term, which was followed by three
interregna before the election of new consular tribunes. In 395 BC, Medullinus was elected Consular Tribune for the fifth time, alongside
Publius Cornelius Cossus,
Publius Cornelius Scipio,
Quintus Servilius Fidenas,
Caeso Fabius Ambustus and
Marcus Valerius Lactucinus Maximus. It is assumed that Medullinus remained at Rome, where he and some of his colleagues continued to manage internal affairs. Meanwhile, two brothers, Cornelius Maluginensis and Cornelius Scipio, were entrusted with the campaign against the
Falisci, which did not produce any concrete results, while Valerius Lactucinus and Quintus Servilius were allotted the campaign against the town of
Capena, which was ultimately forced to sue for peace with Rome. In Rome itself, however, disputes over the division of spoils taken in the fall of Veii from the year before continued to rage, when another controversy was ignited, arising from the proposal of the
Plebeian tribune Titus Sicinius to transfer part of the Roman population to
Veii, to which the Roman senate strenuously objected. ==Final two consular tribunates==
