1st century in the context of Galba

The gastraphetes (Koine Greek: γαστραφέτης, lit. 'belly-releaser'), also called belly bow or belly shooter, was a hand-held crossbow used by the Ancient Greeks. It was described in the 1st century by the Greek author Heron of Alexandria in his work Belopoeica, which draws on an earlier account of the famous Greek engineer Ctesibius (fl. 285–222 BC). Heron identifies the gastraphetes as the forerunner of the later catapult, which places its invention some unknown time before c. 420 BC.

Unlike later Roman and medieval crossbows, spanning the weapon was not done by pulling up the string but by pushing down a slider mechanism.

Roman glass objects have been recovered across the Roman Empire in domestic, industrial and funerary contexts. Glass was used primarily for the production of vessels, although mosaic tiles and window glass were also produced. Roman glass production developed from Hellenistic technical traditions, initially concentrating on the production of intensely coloured cast glass vessels.

However, during the 1st century AD the industry underwent rapid technical growth that saw the introduction of glass blowing and the dominance of colourless or 'aqua' glasses. Production of raw glass was undertaken in geographically separate locations to the working of glass into finished vessels, and by the end of the 1st century AD large scale manufacturing resulted in the establishment of glass as a commonly available material in the Roman world, and one which also had technically very difficult specialized types of luxury glass, which must have been very expensive, and competed with silver and gold as elite tableware.

The first millennium of the anno Domini or Common Era was a millennium spanning the years 1 to 1000 (1st to 10th centuries; in astronomy: JD 1721425.5 – 2086667.5). The world population rose more slowly than during the preceding millennium, from about 200 million in the year 1 to about 300 million in the year 1000.

In Western Eurasia (Europe and Near East), the first millennium was a time of great transition from Classical Antiquity to the Middle Ages. The 1st century saw the peak of the Roman Empire, followed by its gradual decline during the period of Late Antiquity, the rise of Christianity and the Great Migrations. The second half of the millennium is characterized as the Early Middle Ages in Europe, and marked by the Viking expansion in the west, and the continuation of the Byzantine Empire (Eastern Roman Empire) in the east.

The Aquitani were a tribe that lived in the region between the Pyrenees, the Atlantic Ocean, and the Garonne, in present-day southwestern France in the 1st century BC. The Romans dubbed this region Gallia Aquitania. Classical authors such as Julius Caesar and Strabo clearly distinguish the Aquitani from the other peoples of Gaul, and note their similarity to others in the Iberian Peninsula.

Their old language, the Aquitanian language, was a precursor of the Basque language and the substrate for the Gascon language (one of the Romance languages) spoken in Gascony. Between the 1st century and the 13th century, the Aquitani gradually adopted the Gascon language while part of the Roman Empire, then the Duchy of Gascony and the Duchy of Aquitaine.

The Syriac alphabet (ܐܠܦ ܒܝܬ ܣܘܪܝܝܐ ʾālep̄ bêṯ Sūryāyā) is a writing system primarily used to write the Syriac language since the 1st century. It is one of the Semitic abjads descending from the Aramaic alphabet through the Palmyrene alphabet, and shares similarities with the Phoenician, Hebrew, Arabic and Sogdian, the precursor and a direct ancestor of the traditional Mongolian scripts.

Syriac is written from right to left in horizontal lines. It is a cursive script where most—but not all—letters connect within a word. There is no letter case distinction between upper and lower case letters, though some letters change their form depending on their position within a word. Spaces separate individual words.

Táin Bó Cúailnge (Modern Irish pronunciation: [ˈt̪ˠaːnʲ bˠoː ˈkuəlʲɲə]; "the driving-off of the cows of Cooley"), commonly known as The Táin or less commonly as The Cattle Raid of Cooley, is an epic from Irish mythology. It is often called "the Irish Iliad", although like most other early Irish literature, the Táin is written in prosimetrum, i.e. prose with periodic additions of verse composed by the characters. The Táin tells of a war against Ulster by Queen Medb of Connacht and her husband King Ailill, who intend to steal the stud bull Donn Cuailnge. Due to a curse upon the king and warriors of Ulster, the invaders are opposed only by the young demigod, Cú Chulainn.

The Táin is traditionally set in the 1st century in a pagan heroic age, and is the central text of a group of tales known as the Ulster Cycle. It survives in three written versions or "recensions" in manuscripts of the 12th century and later, the first a compilation largely written in Old Irish, the second a more consistent work in Middle Irish, and the third an Early Modern Irish version.

The Pilate stone is a damaged block of carved limestone, with dimensions 82 cm × 65 cm (32 in × 26 in), which bears a partially intact inscription attributed to Pontius Pilate, a prefect of the Roman province of Judaea in the 1st century AD. It was discovered at the archaeological site of Caesarea Maritima in 1961.

The Wielbark culture (German: Wielbark-Willenberg-Kultur; Polish: Kultura wielbarska) is an Iron Age archaeological complex that flourished on the territory of today's Poland from the 1st century to the 5th century.

The Wielbark culture is associated with the Goths and related Germanic peoples, and played an important role in the Amber Road. It displays cultural links not only with its neighbours, but also with southern Scandinavia. The Wielbark culture replaced the preceding Oksywie culture on the lower Vistula in the 1st century, and subsequently expanded southwards at the expense of the Przeworsk culture, which is associated with the Vandals. This expansion has been associated by historians such as Peter Heather with the contemporary Marcomannic Wars. By the late 3rd century, the Wielbark culture had expanded into the area of the upper Dniester, where it possibly influenced the Chernyakhov culture to its south, which encompassed a large area between the Danube and the Don River.

100 (C) was a leap year starting on Wednesday of the Julian calendar, the 100th year of the Common Era (CE) and Anno Domini (AD) designations, the 100th year of the 1st millennium, the 100th and last year of the 1st century, and the 1st year of the 100s decade. As of the start of 100, the Gregorian calendar was 2 days behind the Julian calendar, which was the dominant calendar of the time.

In the Roman Empire, it was sometimes referred to as year 853 ab urbe condita, i.e., 853 years since the founding of Rome in 753 B.C. The denomination AD 100 for this year has been used since the Early Middle Ages, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Langkasuka was an ancient Malay Hindu-Buddhist kingdom located in the Malay Peninsula (in modern-day Thailand). Langkasuka flourished from the 2nd century to the 15th century as the oldest kingdom in the Malay Peninsula, believed to have been established by descendants of Ashoka the Great. The name is Sanskrit in origin; it is thought to be a combination of langkha for "resplendent land" -sukkha for "bliss". The kingdom, along with Old Kedah, is among the earliest kingdoms founded on the Malay Peninsula. The exact location of the kingdom is of some debate, but archaeological discoveries at Yarang near Pattani, Thailand suggest a probable location. The kingdom is proposed to have been established in the 1st century, perhaps between 80 and 100 AD.

According to the legend given in the Kedah Annals, the kingdom was founded and named by Merong Mahawangsa. Another proposal suggests that the name may have been derived from langkha and Ashoka, the Mauryan Hindu warrior king who eventually became a pacifist after embracing the ideals espoused in Buddhism, and that the early Indian colonizers of the Malayic Isthmus named the kingdom Langkasuka in his honour. Chinese historical sources provided some information on the kingdom and recorded a king Bhagadatta who sent envoys to the Chinese court.
