AntiquitiesIn this section you can find a set of miscellaneous interactive tools for Greek and Roman antiquities. For demo purposes, you can find all of these tools in this app, even if most of them were created as an editing aid for Cadmus users.

Please note that at this time the app is under development (migrating from older technologies), so you will find only a subset of the planned sections. Here you can find a short help for using the web application, organized by its sections.

Measurement Units Converter

This section allows you to quickly convert between several measurement units of the ancient Classical world. These units are grouped into families: linear, surface, weight and capacity measurement units; also, they can be filtered by culture (e.g. Greek, Roman, Egyptian, etc.)  and/or group (e.g. Attic system, Phidonic system, Alexandrian itinerary system, etc.).

You can convert from any unit to any other unit(s) at once, and also find eventual multiples of a base unit in its culture. The latter function can be useful in some specialized fields: for instance, in Latin epigraphy most artifacts are of course based onto the Roman measurement system, which for the linear family is based onto the pes (foot), equal to 29.6 centimeters (about 11.65 inches). This can be a useful indication when restoring texts, as it often happens that the epigraphical support had some "round" measures, of course in Roman terms, like e.g. 2 pedes by 1. Also, of course collecting measurements about artifacts give much more sense when converted into the contemporary metrical system rather than using our modern ones: 29.6 centimeters is not "round" for us, but it was just 1 pes in Roman age.


To convert:

  1. select the source unit: select a family, and eventually use the culture and/or group filters to shorten the units list. pick one unit from this list, and click the from button. This sets the source unit.
  2. enter a value for the source unit. This is the value to convert from.
  3. repeat the procedure described under (1) to select a target unit, but this time click the to button. The unit is added to the targets list, which contains all the target units with their value as converted from the source value. Add as many targets as you want. If you change the source value, click the refresh button to update the converted values. To clear all the targets click the clear button.

Multiple detection

To detect potential multiples or submultiples of a given value in a specific culture:

  1. select the source unit, as described above for conversion, e.g. centimeters. Note that the source unit does not need to belong to the same culture or group.
  2. enter a value for the source unit, e.g. 60.
  3. select the desired culture in the culture filter.
  4. click the multiples button. All the potential (approximate) multiples of the base unit for the selected culture are listed at the bottom (with their count). To clear these results use the clear button.

Eras converter

This converter allows you to convert between the most known eras of the Classical world. Just select a conversion type, enter the value to be converted, and click the convert button. The latest 10 results are kept in a list; you can clear this list by clicking the clear button. Available conversions are:

  • Julian calendar to Gregorian calendar: enter a "standard" abbreviated Julian calendar date like e.g. a.d. iv kal apr to get the corresponding Gregorian calendar date.
  • Gregorian calendar to Julian calendar: enter a Gregorian calendar date like e.g.2014-08-11 to get the corresponding Julian calendar date.
  • ab urbe condita to Gregorian calendar year: enter an ab urbe condita year to get the corresponding Gregorian calendar year. The AUC year can be expressed either with Roman and Arabic numbers.
  • Gregorian calendar year to ab urbe condita year: enter a Gregorian calendar year to get the corresponding ab urbe condita year.
  • Olympiad to Gregorian calendar year: enter an Olympic era in the format N.N where the first N is the olympiad number and the second the year (1-4) to get the corresponding Gregorian calendar year.
  • Gregorian calendar year to Olympiad: enter a Gregorian calendar year to get the corresponding Olympiad number.
  • Byzantine era year to Gregorian calendar year: enter the year in Byzantine era to get the corresponding Gregorian calendar year.
  • Gregorian calendar year to Byzantine era year: enter a Gregorian calendar year to get the corresponding Byzantine era year.

Sigla Resolver

This tool allows you to quickly lookup the resolutions of the most used epigraphical abbreviations for both Latin and Greek inscriptions:

  1. enter one or more abbreviations, separated by commas (e.g. d.d., d.m.).
  2. click the resolve button. For each abbreviation, its resolution(s) are listed.

Roman Calendar

A perpetual Roman calendar (just for fun). To get a month, select it, specify the first nundinal letter of the year, and the year number. The list of fasti is there only for demonstrative purposes, and is essentially derived from the Fasti Praenestini. Its abbreviations are:

quando rex comitiavit fas
quando stercum delatum fas
nefastus, feriae publicae (?)

Roman Emperors Finder

This section allows you to quickly find all the Roman emperors whose titles match the ones you specify. Even if there are more functionalities on this subject, not yet exposed by the application user interface, this is the essential one for helping in finding a Roman emperor given a part of his titles set (it. titolatura imperiale). This can be useful when dealing with partially preserved inscriptions where the emperor name is not found but one or more of his titles are present.

To find matching emperors, just specify the titles in the filters pane and click the find button.
