Five of the Dead Sea Scrolls are available to browse for free online, thanks to a joint project between Google and the Israel Museum in Jerusalem. The scrolls, which are written on papyrus and parchment, are believed to date back to 150BC and contain the oldest copies of many Biblical texts. Google's ultra-high resolution scanning lets you pick out every crease and blemish in each scroll, and helpfully provides an instant English translation when you highlight a section.

Ancient Rome in 3D
Want to see what ancient Rome really looked like, rather than trying to imagine it from photos of ruins? Then download Google Earth, open the Gallery layer and select the Ancient Rome 3D option. This will take you back to 320AD, where you can explore more than 6,000 3D buildings, such as the Forum, the Colosseum and the Temple of Vesta, including some you can step inside for a closer poke around.

History of places from above
Google Earth also features a 'Historical imagery' tool that lets you see how an area has changed over time. When you're viewing a place from above, click the clock icon on the toolbar and drag the slider bar to the left to move back in time or to the right to move forward. The aerial photography will change accordingly, where available, and sometimes the imagery goes back as far as the 1930s.

Historical Google Maps
Map collector David Rumsey has combined 120 historical maps from around the world with contemporary Google maps to let you travel back in time without losing your bearings. For example, you can view an incredibly detailed map of England and Wales from 1790, maps of Australia and New Zealand from the 1840s, and a depiction of Tokyo in 1680. You can use the transparency slider to merge the old data with its present-day view.
