Titus Oates (15 September 1649 – 12/13 July 1705) was an English priest known for fabricating the "Popish Plot," a supposed Catholic conspiracy to assassinate King Charles II. Born in Oakham, Rutland, Oates was the son of Samuel Oates, a Baptist minister. Despite a less than stellar academic record, he gained a license to preach in the Church of England through false claims and later became a naval chaplain. Oates' controversial life included accusations of perjury and buggery, leading to arrests and escapes. He eventually joined the household of the Catholic Duke of Norfolk before converting to Catholicism himself. Oates was involved with the Jesuits in France and Spain but was expelled from training for the priesthood due to his incompetence and blasphemous behavior. Later, he collaborated with Israel Tonge to fabricate a manuscript accusing the Catholic Church authorities in England of plotting to assassinate King Charles II. Despite his unsavory reputation, Oates's confident performance and superb memory led to the conviction of several individuals implicated in the supposed plot. Oates's legacy is marred by his dishonesty and controversial actions, making him a polarizing figure in history.

The Titus cut, also known as coiffure à la Titus, was a popular hairstyle in late 18th-century France and England. This style, characterized by short layered cuts and curls, gained prominence in 1791 when French actor François-Joseph Talma, portraying Titus in Voltaire's Brutus, popularized it. The Titus cut marked a departure from the elaborate hairstyles and wigs of the era, resonating with the simplicity and classical aesthetics associated with the French Revolution. Initially a men's style, it quickly gained traction among women, with the Journal de Paris reporting that a significant number of elegant women adopted the Titus cut. The style, often referred to as coiffure à la guillotine in England, was linked to the revolutionary fervor. Despite its popularity, the Titus cut fell out of fashion by the 1810s. While it remained influential into the 19th century, it eventually waned in popularity.

Titus Flavius T. f. T. n. Clemens (d. AD 95) was a prominent Roman politician and cousin of Emperor Domitian, serving as consul alongside Domitian in AD 95. Despite his influential connections, Clemens faced a tragic fate, being executed shortly after his consulship, allegedly for atheism, though the exact circumstances remain unclear. Over time, he came to be regarded as an early Christian martyr. Clemens hailed from a distinguished lineage, with familial ties to emperors Vespasian, Titus, and Domitian. He was besieged in the capitol as a child, and his brother was put to death by Emperor Domitian, purportedly due to the emperor's affection for Clemens' wife, Julia Flavia. Clemens was also married to his second cousin, Flavia Domitilla, and had two sons whom Domitian intended to succeed him. His execution, associated with a charge of atheism, and his wife's subsequent banishment to Pandataria have sparked scholarly debates about his potential conversion to Christianity. Some scholars even identify Clemens with "Ketia bar Shalom," a Roman senator described in the Talmud as having converted to Judaism.

Titus Flavius T. f. Sabinus, a Roman eques, was the father of the renowned emperor Vespasian. Hailing from Reate in the Sabine region of Italy, Sabinus was the son of Titus Flavius Petro and Tertulla. Initially, he served as a customs official and subsequently as a respected banker in the province of Asia, where he was honored with statues dedicated to his integrity. Later, he continued his banking career at Aventicum among the Helvetii in Gaul, where he eventually passed away. Sabinus was married to Vespasia Polla, and together they had at least two sons, including the consul Titus Flavius Sabinus, and the future emperor Vespasian, as well as a daughter, Flavia Vespasia, who sadly passed away in infancy. His life and lineage are significant in Roman history, leaving a lasting impact on the empire.
